PERIODICAL Radioteohnika," , fase.10, 79-80 (1956)
Issued: 11 1956
The conference was held at the Leningrad Electrotechnical Institute
W.I.ULJANOV (Lenin).
In his lecture on "Semiconductors in Modern Technology" NASLEDOV said that
although Russian physicists attained some success in this field, the level of
semiconductor technique already attained in other countries has not been
attained in Russia.
PETROV spoke about the methods of obtaining super-pure germanium and silicon
as well as about a number of new substances with crystalline structure similar
to that of germanium and silicon. Among them particularly the antimonide of
aluminium is worth mentioning. It will be widely used in devices intended to
be used at a surrounding temperature of 350 0 C. The antimonide of indium will
be used in photoelements which are highly sensitive to infrared radiation.
BOGORODICKIJ declared that the use of the titanate of zirconium, of zelsian,
and of the stannate of calcium promotes the development of a condenser
ceramic with very high thermoatable properties, while losses at high dielectric
transmissivity are low.

VERBICKAJA spoke about new types of nonlinear condenser varioonds and the range
of their application, as i.,e, as dielectric amplifiers, in voltage stabilizers,
frequency modulators, and similar devices.
ORE6KIN delivered a report on thermistores at high temperatures. He pointed. to
the possibility of using thermistores of aluminium, oxide, magnesium; and some
other materials.
A large number of lectures was devoted to ferrites.

Title Character of the Temperature Dependence of Dieleetric
Losses in the Polarization of Ionic Compounrls.
Orig Pub Zh. tekhn. fiziki, 1956, 26, No 9, 1884-1889
Abstract A study was made of the temperature dependence of the
dielectric losses (tan E ) at, various fi.,equencies, of
certain ionic compounds, namely glass (boric anhydride,
boron-sodium, boron-barium, commercial allmli-less sili-
cate-barium, and silicate-lead glass) and ceramic mate-
rials ("radio" porcelain, steatite, "ultra!-porcelain
etc.). It is shown, that unlike the preimiling idea of
the presence of a region of temperatures in which tan
retains a constant value, a temperature dependence of
tan 9 is observed for all the investigated substances.

The character of this dependence differs for various
materials. In connectionp with this doubt is raised
concerning the advisability of subdividing the losses
in ionic compounds as proposed by T.I. Skanavi, into
(a) structural, (bj relaxational, and (c) conduction
losses. It is suggested that the dielectric losses
can be reduced to the following physical processes:
(1) relaxation during polarization,
~2 relaxation during electric conduction,
3~ ionization of the substance.

TITLE On the Problem of Anomalous Polarization in the Polyarystalline
Peroxide of Titanium.
PERIODICAL ~Urn.techn fis 26, fase. 9, 1690-1901 (1956)
Issued; 1; / 11957 reviewed. 10 / 1956
In connection with contradictions found in literature the authors investigated
the influence exercised by admixtures of oxides of the metal groups II., III.,
and V. on the electric properties of polyorystalline peroxide of titanium.
Chemically pure reagents were used as additions of foreign oxides. The samples
were mixed in an agate mortar with distilled water, after which they were dried
and pressed. The thickness was 1,0 to 1,5 mm. Burning was carried out in electric
silican carbide ovens at 1200 to 14500 C in platinum vats. Burnt-in silver layers
served as electrodes. The degree of purity was controlled by spectral analysis
and structure was controlled by X-ray analysis. One of the basic problems is that
of the characteristic of the spectrally pure peroxide of titanium with a permitted
low content of admixtures. A table contains the data on the dielectric constant
and the tgb for various frequencies at room temperature as well as for a specit-
ic space resistance at 1000 0 of the titanium peroxide of various brands. A curve
represents the dependence of E and tg6 on temperature. The same was done by
further curves for titanium peroxide with various admixtures. These curves show
that titanium peroxide with admixtures of Nb 205and CaO has anomalous electric
properties. Additions of Al 203? Fe203and ZrO2 remove these anomalies.

ally purified (spectrally pure) titanium peroxide is characterized by
important electric properties within avide temperature- and frequency range, and
possesses no anomalous electric properties.
2.) An anomalous polarization in TiO 2 is found in the cases of additions of CaO
and Nb2050 which is connected with the process of partly recomposing the TiO 2 in
the presence of these oxides.
3.) An anomalous polarization occurs also in pure titanium peroxide which has no
foreign admixtures, namely if it is treated thermally until it attains a light
blue color in a reducing atmosphere.
4.) The additions of Al203 and Fe203 to titanium peroxide, providing the latter
contains Nb205 or CaO, lead to a considerably lower restoration of TiO 2 because
of the compensating effect of the trivalent oxides. In this case no anomalous
polarization is observed.
5.) An anomaly of Ue electric properties of titanium peroxide with admixtures
is observed in the case of technical and acoustic frequences. Within the range of
radio frequences the tgb does not increase but is reduced in the case of all
compounds.
6.) A carefully carried out X-ray structural analysis of titanium peroxide with
admixtures of foreign oxides (Cao, Bao)produced no loosening of the crystalline
rutile lattice.

Zurn.techn.fia, 26, fase.9, 1890-1901 (1956) CARD 3 PA - 1381
7.) It has been proved by experiment that within the range of sufficiently
large concentrations of Fe2031 Nb205 and Al203 additions the presence of a
phase - that of rutile - becomes noticeable. The solid solution occurs dis-
tinctly in addition of Rb 205*
8.) If the low frequences, at which the anomalous processes of polarization
in titanium peroxide with admixtures have been observed, are taken into
account together with the conductivity of the anomalous TiO 21 it may be assumed
that the most probable mechanism of dielectric losses is
the electron-relaxation mechanism.

ABSTRACT: In co-nection with drastically increased requirer-nezits for electrical
properties of high-f:req7aency insulation, a need I-as arisen for careful study of
dielectric losses in ionLic compounds at high frequencies. To this end, losses
in some borate xad silicate simple glasses, and also in some types of H-F
ceramics, were studied anew. Experimental data obtained for a wide range of
temperatm-res (from -2000 to 45000G) and frequencies (up to 1010 cps) testify,
accordiz,-g to the author, that losses in polarization of ionic compo'-"Ids are due

ABSTRACT: Recently a series of lectures was held in Leningrad on
small-size radio parts. The lectures were organized by
NTORiE imeni A.S. Popov. The lectures dealt with materils
for producing small-size receivers, capacitors, resistors,
transformers, induction coils, printed circuits and techno-
logical questions. Some of the most interesting lectures
were: "Physics and Technology of Electrotechnical Materials
Used in the Manufacture of Radios" by N.
immi
-
"Capacitors Made of Paper and Tape" by'f. Zakgeym; "Fon-
wire Resistors" by B. Gallperin ; 'Wagnetic Materials" by
V. Mealkin. In the reports it was pointed out that there
is a tendency to reduce the dimensions of the radio parts.
Tantalum capacitors were listed as example for the effort
Card 1/2 made in this direction. However, there are certain obstac-

cles in the development of new, small-size parts. Fre-
quently, such parts are not manufactured immediately after
their development is completed, because there are no orders
from the consumers who do not know that these parts have
been developed. Therefore it is necessary to publish in-
formation on new developments in periodicals on electronics,
radio engineering, etc.

packing in the lattice. The mijority of compounds is character-
ized by a dense ion packing in the lattice and by the electron
character of electric conduotirity. At the same time, these
crystal formations differ according to the energetic speotr= of
the forbidden zone. The narrower the band of the forbidden zone,
the more do the admixtures of lea3 influence electric propertie3

electric conductivity of ion dielectrics, among them also those
of electroceramics, are pointed. out. Frequently they are superim-
posed. The experiments carria4 out by the authors showed that the
character of the electric noonductivity of ior.-dielectries in ceram-
ics can often be determined iu a simple manner by comparing the
experimental depen3ence of the current on time in silver- and
platinum- or gold electrodes. This method is based on the fact
that, in the case of silver electrodes, a diffusion of silver in--
to the ceramics is observed, whereas in the case of platin= eler.-
troaes this is hardly ever the case. A further table gives a clas-
sification of aieleotrio losses in electrotechnical ceramics. The
latter table also gives the properties for ceramic woriting materi.-
als as laid down in GOST 5458-157. There are 3 figures, 5 tables,

ABSTRACT; To meet increasing damands for porcelain insulators of
good mechanical properties, Corundo--mullitG ceramic
material KM-l has been developed, as described in
Blektrichostvo, 1954, Nr 7. In chemical, mineralogical
and phase composition this material is uniike high-voltage
porcelain. The crystalline phase consists of about 707'0r
corundom and mullite. The vitreous phase is similar in
chemical composition to BaO.Al 203 .2SiO2 and CaO.AlP-03.2SiO2.
The fired material has a uniform fine grained structure.
Production trials on material XM-l for the manufacture of
high-voltage insulators were carried out at the Proletariy
Works. The main physical-technical properties of
material KK-1 and of high-voltage porcelain are given in
-ard 1/3 Table 1. It will bo seen that the mechanical properties

of KII-1 surpass those of porcelain, The influence of
fineness of milling of the materials usod in Fl'-l is
shown in Table 2t with roj~qeat to hardening tomporaturo
and i,,iechanical s rength. As the material becomes
coarser the hardening temperature rises and the strength
decreases somewhat. Samples of kaolin from three
different sources were used as constituents; it was
found that the technological characteristics of M.,'-l were
practically unaffected. Samples fired at temperatures
of 1320 - 13800C were observed to be very strong. The
types of high-voltage insulators that were manufactured
for proctil-tion trials are described. Because of the hard-
ness ol KM-11 difficulty was experienced in grinding it
with the abrasives ordinarily used for ceramics. Glazes
normally used for porcelain can be used for

ABSTRACT: This paper is limited to an investiCation of the
component of the dielectric losses which is cai~,sed
by ions. The authors are of opinion that it is more
correct to connect the dielectric losses directly
with the crystallochemical features of the crystal lattice,
even the more as the lattice energy is determined by
just these peculiarities. (This replaces the conception

electric losses of a number, as great as possible, of
alkali-halide crystals, giving special importance
to a series of compounds not investigated in tbe
papers cited by references 1,2,and 3. Mixtures of
alkali-halide crystals were also included in the work
and their properties were compared with those of
several silicate- and titanium- c ntaining systems.
Summary: 1) The nature of the t9 t versus concentration,
versus temperature and frequercy, and versus time
functions may be re,-arded to constitute one of the
criteria serving in the estimation of the interaction
of components and of structural transformations of the
system. 2) When polarization by ionic relaxation
is considered the dielectric losses are determined by
the defects in the crys'al lattice. These defects are
not taken into account by the formula for the lattice
energy. Hence tg E in, a great number of alkali halide
crystals does not correspond to the lattice energies. 3)

TITLE- The Electric Properties of a Dielectric With a Variable Number
of Relaxers (Elektricheakiye avoystva dielel~trika s peremennym

PERIODlCAL: Doklady Akademii nauk SSSR, 1958, Vol. 12o, Nr 3, pp. 48'j-49COUSA
ABSTRACIs The various conditions of the dependence of the amount of
relaxation polarization on the time necessary for it to commence
are discussed first. If the field in the dielectric changes
sinusoidally with the circuit frequency as time progresses, the
dielectricity constantF_ may for a given frequency be less than
that which the dielectric would have in a constant field. An
expression is given for the frequency at which the dependence of
tg6 upon W has a maximum. The relaxation time t is assumed ex-
ponentially to depend on the temperature. The voluminous experi-
mental material available shows that the temperature maximum of
tgS , which is predicted by the theory, can in some cases not be
determined experimentally. The discrepancy between theory and
experiment mentioned in this paper is due to the simplifyine
assumption that the number of relaxers is independent of temper-

relaxers in the case of a temperature increase. According to
Skanavi (Ref 1) the ions are in a "consolidated" state at low
temperature, from which state they can be liberated when the
dielectric is heated. The authors here investigate the case in
which the number of relaxers increases with rising temperature.
Pirst, it is assumed that the dependence of relaxation polarizaticn
P on the temperati;re T in a constant field is determined by the
formula P - p0e-U/kT. Here U denotes the relaxation energy of
the relaxer and PO - a constant. The aforementioned assumption
-U/kT
is replaced by the more complete assumption V, - K0 e , where
k0 denotes a constant. If the number of relaxers increases with
rising temperature, the temperature maximum of tgS is found to
occur at a higher temperature than if the number of relaxers is
constant. In some cases the reduction of the number of relaxers
with increased temperature may have the follwoing consequences:
a) Increase of the dielectric constant in the case of rising
temperatures b) Lack maximum of to& during the course taken

investigations, as well as theinve'stigation of the electric
conductivity, are listed in table 2 for natural wollastonite,
and in table 3 for synthesized wollastonite. Table 1 shovis the
dependence of the inclination tangent of the dielectric losses on
the burning temperature of the raw materials. Figures 2-5 show
microphotographs of wollastonite rocks and synthesized wollastonitep
while figures 6-8 show X-ray pictures of these wollastonites.
Furthermorep the electric and physico-mechanical properties of
radioaeramic materials made of wollastonite are given. Figure 9
represents the results of comparative examinations of the heat
resistance of samples of steatite material and wollastonite.
As can be seen from these results, the heat resistance of the
wollastonite samples is much higher. Investigations showed that
the wollastonite rocks from the Kansay and Lyangar deposits can be
used as a raw material for the production of electrotechnical and
other types of ceramics. There are 9 figures and 3 references,

PERIODICAL; Zhurnal tekbnicheskoy fiziki# 1960, Vol.30, No.6p pp.699-704
TEXT: With reference to the papers (Refs. 1, 2) investigations are described
of a series of clear crystalline phasee and their mixtures as applied in
radio ceramics. The purpose of these investigations was to obtain furt%er
data on the character of the temperature dependence of the temperature co-
efficient M of the dielectric constant in a wide temperature range. The
ceramics which were investigated are listed and the production of the
samples and the mode of the experiments is described. Since in many di-
electrics E varies strongly with temperature, TKa was calculated in every
case for a narrow range of temperature of 15 4 200C. This coefficient has
the symbols TKE d (d - differential). The data obtained by the experiment qK
are given and discussed. Fig. 2 gives the- temperature dependences of the

investigated compounds in the range of (-150) 4 (+150)oc. It is seen that
for most of the ion dielectrics (polyorystalline ceramics, glasses, mica)
TKEd decreases with a drop in temperatureg but in some cases (calcium
stannate, calcium zirconate) a minimum of TK&d is observed. Thoso dielectrics
in 'which TKE is subject to a particularly strong change (up to 2.5 - 3 times)
can be divided into two groups. These are explained in detail. On the basis
of the investigations made it can be assumed that iD the various ceramic
dielectrics a relaxation polarization at low temperatures exists, i.e., in
ceramic dielectrics with and without titanic dioxide. The paper by V. A.

A semi-graphical method of calculating the thermal
breakdown voltage of high-frequency insulators
PERIODICAL: Elektrichestvo, no.12, 1961, 63-68
TEXT: A_ semi-graphical method is proposed to overcome the
mathematical difficulties of calculating the thermal breakdown
voltage of insulators and capacitors, particularly ceramics. it
is assumed that K (the thermal conductivity of the dielectric),
s (its permittivity) and tan 6 are given as simple functions of
coordinates and temperature. In many practical cases the
insulator can be represented as a sheet of material with a uniform
electric field applied parallel to a face of the sheet. One side
of the sheet is ideally thermally insulated and the other is
exposed to air, so that heat flow is perpendicular to the
surface and to the electric fields. An element of unit surface
area within the insulator is considered. An expression is derived

for the heat evolved in this element and it is equated to an
expression for the heat dissipated from the outer surface of the
element in contact with air. A graph is plotted (Fig.4) of 1,
as a function of temperature, where Tj differs from the
electrical conductivity of the material by a constant faotor and IS
given by the expression
9 t9 6f (W./cm kV2 (18)
1.8010 +6
where f is the frequency. From a point in the abscissus
corresponding to ambient air temperature TA, a tangent is drawn
to intersect the curve at the point VE . Then the temperature of
the hottest point in the element at the instant of breakdown lies
between V-1 and Tl"~ where q) = TM - TA; 0 = (%/K)D
(N - external heat transfer coefficient; D - thickness).
A graph is then plotted of surface temperature Tn as a function
of applied field strength B to find the point on the curve
corresponding to the maximum surface temperature T (see Fig,,5)-
Then the maximun surface temperature at breakdown Rp is

calculated within certain limits in a manner similar to that used
to determine the maximum temperature in the specimen. The
temperatux-e difference between the hottest spot and the surface can
then be determined within cdrtain limits. The heat dissipated from
unit'surface at a voltage near to breakdown is found and then the
electric field strength is determined that causes this"amount of
heat to be evolved, which is the value required to be found.
The method can be applied to insulators that are air-cooled on
both sides by considering them to be of half thic'-k-ness; it can
also be applied to cylindridal ceramic insulators in a uniform
field provided the radius is great compared with the wall thickness.
I-us application to more difficult cases is discussed. A. worked
example on a simple case shows that the accuracy suffices for
practical purposes.- A-number of general conclusions are drawn.

mentioned having a highly aniaotropic dielectric constant. The arrangement
of the nearest neighbors of Ti and Sn in the lattice and their electron
configurations show that there is a plane covalent bond in TiOi but not in
SnO 2- A model of polarization is proposed for'TiO 2 in.which the elastic
forces do not shorten the interionic distance (below 1-944 R) in the h-0
bond when an external field is applied. This Is due to the covalent bond.
The 0-0 bonds, however, are expanded within each molecule, which leads to a
Ti
displacement of the group as a whole. The anisotropy of the dieleotrio

TOPIC TAM electric conductivity, dielectriop current carrierp solid state#

ABSTIUCT: This'is a survey of existing theories an the subject. The authors
consider a clas4ification of conductivity: first, conductivity not associated with
for=tion of donor or acceptor centers in the lattice, embracing three classical
types -- pure electron, cation-cation, and cation-anion; and, secondly, conductivity
associated with the foi~matiou of donor or acceptor centers in the lattice, also ~ '
embracing three types --w- cation-eleetron, anion-electron, and cation-anion-electron.
Each type is analyzed briefly. The authors note tha-t one type is commoWy super-
imposed on another, but that one is generally aomin=t, depending on the tempars.-
ture. They conclude that a consideration of the facts -- the materials and
environmental state -- permit the determination of the mechanism of conductivity in
any specific instance.

diameter and 3-mm thick; the electric field intensity, the maximum
temperature, and the time of exposure to the field were variable.

ABSTRACT* Rutile'single crystals alloyed with 0.005-1.0% niobium were doubly
annealed in air at 800*C for 3 hr and slowly cooled. Specimens cut from the crystals
were tested for electric conductivity and Hall effect at 84-500*K. It was found
that alloying rutile with 0.005-0.0511. niobium sharply increases its conductivity.
Further increases in concentration, however, produce saturation. To test the effect
of reduction on the properties of alloyed rutile) the specimens were reduced in a
vacuum of 4-10-3 mn Hg at 900*C for 20 min. The conductivity of an unalloyed control
specimen increased twelve orders of magnitude, while that of an alloyed specimen in-
creased only 1.2-1.5 times. The change in Hall effect was similar. It was also
determined that semiconducting rutile alloyed with niobium is more resistant to
