decomposition of the first was observed in the system. The
stability of the compounds decreases,with the increase in
temperature. It is remarkable that in this case the values of
the heats of formation (on the average 9,22 kcal per I g mol SO 2)
are lower than in the normal case of coordination compounds.
Furthermore, it is of interest that at -100 (boiling point of
so2) the discussed compounds ha-.9 the characteristic features
of solid soliations and can exist only at increased Pressure.

TITLE: On the Role of Fluoride Compounds in the Transport of Beryllium
and the Formation of Phenacite (0 roli ftoristykh soyedineqiy

PMODICAL: Geokhimiya, 1959, Ur 19 pp 20-26 (USSR)
ABSTRACT: The authors synthesized phenacite from beryllium - and silicon
oxide. The following materials served as mineralizers:
NaF, BeF2 and the fluoberyllates of alkalis. The latter
preparations were supplied by N. S. Tamm and L. 1-1. Mikheyeva.
A carefully produced mixture was sealed in quartz ampoules
(Figs 2 and 3) and heated in shaft furnacen. The temperature
regulators BRIT-47 and EPD-17 were used in this process. Ex-
periments at different temperatures and with different mineral-
izers (Tables I to 3) gave the following results: the formation
of phenacite from BeO and SiO 2 in the presence of fluoberyllates
is a heterogeneous reaction, i.e. via the gaseous state. The
authors assume the following mode of formation:

Because of the transport reactions phenacite can be "over-
distilled". The paragenesis of phenheite in the various deposits
and the morpholoqical similarity of synthetic and natural
crystals (Pigs 4 to 7) suggest that fluoberyllates play a lead-
ing part in the andogeneous formation of phenacite. The authors
express their gratitude to A. A. Beus for reviewing the results.

ABSTRACT-. Unlike vanadium sulfides and selenides the system of tellurides
has not yet been investigated in its entirety. The synthesis
of vanadium-tellurium compounds: V and Te in
various ratios were-heated for 500 hours up to 8000 in quartz
ampoules which were closed by melting in vacuum. Temperature
gradually decreased to room temperature for a period of 400
hours. This was done in order to cause the formation of com-
pounds which are unstable at higher temperatures. The samples
obtained were radiographically investigated. The V lines
disappear already with a composition VTeO.200 The roentgeno-
gram of this t~ phase remains unchanged up to We Even

does not occur. Hence a tetrahedral coordinatior -f the atoms
in this phase is assumed. Since the atom radii of Te and V
are almost similar one can be substituted for the other in
the crystal system without the interference lines being shiftel.
At VTeO.82 the diffraction picture changes suddenly. The .
(~ phase is formed,the range of which lies between VT9 0.82 and
VTei.270 At VTe 1-50' corresponding to V,Te 3' the next phase
follows the width of which, however, could not be found be-
cause the roentgenograms of the next sample (VTe 1.63 ) were
useless. VTe2 is characterized by its angles of reflection.
With a higher tellurium content there are again lines of
elementary tellurium. Thus the sample with the stoichiometric
ratio VTe3 indicates only the lines of VTe2 and Te. Conse-
quently, higher tellurides are not formed. The Debye roent-
genograms of the f9 and phase could not be explained. The
~,phase showed more than 100 lines, the phase 60 - 65. Con-

structure of these phases is to be assumed. V2Te 3 probably
is monoclinic. At We22modifications were found; the one is
scale-like, the other forms elastic threads. Debye diagrams
of these thread-like crystals were plotted (Table) and the
axes were measured. It was found: a = 6.47 kx, b- 7.28 kX
and c. 6.26 kx (rhombic syngony). Diagrams of the conductivi-

maxima for the phases % and 5and for We 2' The conductivity
of all samples decreased after three months, however, it
remained so high that a metallic character of the bond in
the vanadium tellurides may be presumed in view of the weak
electromotive force. There are 3 figures, I table, and 9

ABSTRACT: In the state diagrams of systems containing beryllium fluoride,
some ranges are known within the limits of which the malts
harden like glass when cooling (Refs 1-5). The authors
investigated the optici!j, properties of several types of glass
of ber-yllium fluoride.Xb The pure glass type of beryllium-,
fluoride was compared in a chemical and optical respect ' h
the above types of glass. A platinum crucible was used Art
melting which was placed into a closed steel- or quartz con-
tainer. At a high temperature (1,000*0a glass is formed
which has a higher degree of transparency, and Is free of
air bubbles. The authors also-prepared glasses by addition
of magnesium-, calcium-, strontium-, barium- and aluminum
fluorides. -They did not succeed in producing glass without
the addition of potassium fluoride. The glass formation

weight) are added. One may start from a mixture of fluorides
as well as from fluorine beryllates, i.e. from K2BeF 49 KBeF3
or f%""'&EFY2BeP2' mixed with fluorides of other metals. Glass
containing beryllium and potassium fluoride can also be molten
in an open dish. If keeping these glass types in open air for
a longer period, a thin dull film forms. Both the glass-like
B012 and glass types containing only BeY2 and KY are very
unstable, and become rapidly dull in open air. The hygroscopy
of these glass types can.be considerably reduced by the addition
of fluorides of bivalent metals. The forming of the dull film
can be irevented by storing in a dry place and by using rubber
gloves. The film ?&n also be ground off. Figure I shows the

ABSTRACTs The tantalum tellurides were investigated. For the production
of tantalum tellurides pure tantalum powder with slight
impurities (niobium 0.3% and titanium 0.1%) and pure
tellurium (99.99%) were used. Ba means of the differential
thermic analysis it was found that the reaction between
tantalum and tellurium begins at J50 0- The sintering of
tellurides was carried out at 800 . X-ray analyses and
determinations of the electric conductivity and of the thermo-
electromotive force were carried out. In the system Ta-Te
the compound TaTe and two compounds of varying composition

ponents during a period of 400 hours at 900 0' and hardening
during a period of 150 hours at 5000 was plotted. The curve
of the specific electric conductivity shows a maximum at the
TaTe3 composition. The electric conductivity of the samples
varies considerably depending on the conditions under which
the eamplao'have been prepared. The curve of the dependence
of the thermo-alootromotiva force on the composition shows
a minimum with TaTe 3* The high value of the specific electric
conductivity and the low value of the thermo-electromotive
force show that the chemical bond in TaTe 3 is semi-metallic.
The preparations with the composition TaTe 0.8-0.5 are unstable
in air. Lower tellurides were not found in the tantalum-
4ellurium system. There are 5 figures and 4 references, 2

TITLE: On the Phenolates of Beryllium (0 fenolyatakh berilliya)
PERIODICAL: Zhurnal neorganicheokoy khimii, 1959, Vol 4, Nr 3,
pp 549-552 (USSR)
A3STRACT: The interaction between beryllium chloride and P-naphthol and
p- and m-cresols has been investigated and the properties of
the resulting phenolates have been described. The reaction of
beryllium chloride with o-, p-, m-cresol takes place at
90-1000C. The interaction of p- and m-cresol with BeCl 2 takes
place under a strong development of HC1. The phenolates of
beryllium are white, amorphous, hygroscopic substances, which
slowly hydrolize In air. Thermographic and radiographic
investigations were carried out. The following phenolat6s have
been prepared: P-naphthol beryllium (Be(OC 10H7)2 and
Be(p-OC7H7)2 and Be(m-OC 7H7)2. The phenolates of beryllium
are slightly soluble in benzene and xylene, stable in ether.

ABSTRACT: The system SrF,-BeF2 was investigated by the method of
differential-thermal and X-ray phase-analysis. Beryllium
fluoride was produced by thermal decomposition of ammonium
beryllium fluoride and strontium fluoride from strontium
carbonate and hydrofluoric acid. For the production of melts
with a content of 0-50 mole % BeF2 SrF 2 and strontium
beryllium fluoride were used. For alloys with 50-97 mole'4
BeF2 melts from strontium chloride and ammonium berylli,im
fluoride were used. Melts with more than 50 mole 16' BeF2 are
Card 1/3 hygroscopic. The phase diagram of the system SrF 2-BeF2 was

plotted. At 8831180 beryllium strontium fluoride forms a
eutectic with strontium fluoride. Strontium beryllium fluoride
melts congruently at 954,+.100, and at 923e0 a polymorphic
transformation occurs. SrBeF4 forms with beryllium fluoride
a eutectic at 582+270. On the thermogram of the melt with

which could not be found by X-ray analyses. The compound
SrBeF4 was determined by X-ray analysis. This compound occurs
in three modifications; oc,~, and r. From an aqueous solution
theP form of SrBeF4 precipitates with impurities of the

PERIODICAL: Uspekhi khiriiii, 1959, Vol 28, fir 1, pP 33-43 OSSEO
ABSTRACT: In this paper the authoreoz repbrts her investigations on
beryllium fluoride compoundo. 'B"eryllium fluoride can be
prepared in various ways. The simplest of' these is the thermal
decomposition of ammonium fluaroberyllate (.,:11 4)2BeF4 (Ref 2).
BeF2 is a poor conductor of electricity in the molten state
(Ref 4). Its structlure if, different from that of other bivalent
metals which crystallize in the same manner as fluorite (CaF 2)
or rutile (TiO 2). All kno-an modifications of BeF 2 are
similar to the structure of SiO 2- Contradictory data are given
in publications for their relative melting temperatures. This
is becaus3 of the fact that the melting process for -BeF 2 is
very complex. The most probable phase diagram for BeF 2 is given
Card 1/4 (Fig 1) on the basis of known melting temperatures and

Beryllium Fluoride and Fluoroberyllates SO-V/74-28-1-2/5
polymorphic transformations. "Por the thermogram for heating
the BeF2 a definite endotherm-ic effect has been observed at
545 - 5500. It has been found by visual. observation that a
partial melting of the BeF 2 takes place at this temperature.
Apparently there are polymeric molecules of varying composition
present in the molten BeF 2 which are very slowly transformed
from one form to another. On the basis of the phase rule this
does not represent a one-component system. Possibly 5450 is the
eutectic temperature in this system. MeF-BeF2-H20 systems.
BeF2 is easily soluble in water. Because of its small size the
beryllium ion has a very strong electrical field and therefore
form numerous complez compounds. With fluorides of alkali
metals BeF 2 forma fluoroberyllates of several types; hie 2BeF 4?
MeBeF MeBe P BeF 2- ion has a tetrahedral structure
31 2 5 4
(hybridization. Sp;)(Ref 15). The solubility of fluoroberyllates
increases with increase in the cation radius (Table 2).
In aqueous solution the BoP 2- ion is partially dissociated,
4
Card 2/4 Beryllium hydroxide precipitates from solutions of BeF 2and

Beryllium Fluoride and Fluoroberyllates SOV/74-28-1-2/5
and barium fluorides. Beryllium is in the first place of the
II. group of the periodic system of Kendeleyev. Its cheaical
properties are similar to those of aluminum, and in the
second group it is most similar to zinc; it differs strongly
from the earth alkali metals. Many compounds of Zn and Be are
Yery similars hydrides, oxides, silicates, and oxyacetates. Of
particular note is the similarity between the structures and
properties of the oxyacetates Be 4O(CII 3000)6 and Zn4 O(CII3cOO)6#
The tendency for Zn and Be to form complex compounds arises
from the appreciable eizes of their ion potentials. These can
be estimated by comparing their crystal-chemical electro-
negativities. Figure 9 lists the values of the electro-
negativities of the group II. metals (Ref 49). The first
striking thing is ihe periodic variation shown, and secondly,
that the electronegativities of Zn and Be are very close. This
also seems to be the reason why Be is more similar chemically
to Zn than to the earth alkali metals. There are 9 figures,
3 tables, and 72 references, 35 of which are Soviet.

precisely as well as in order to determine the possibility of
formation of other compounds in the system beryllium oxy-

compounds formed with 30 . (mentioned above). The decomposition
of the two last mentioned compounds proceeds by the formation
of phases of variable composition. This contrast in assumed to
explain the quicker establishment of the dissociation equilibrium
of the compound with NO2. The dependence of the dissociation

Furthermore the compound obtained was investigated radiographi-
cally, its density and crystalline structure determined. There

ABSTRACT: After a survey of publications (Refs 1-e) concerning sodium-

a thermographic and X-ray investigation. Figure 1 shows the ra-

main raw material for selenium production are the by-produots of non-ferrous

on the electrical properties of selenium rootif4ers. It was found that the
admixtures of many metals introduced in the form of selanides in relatively
low concentrations (0.1-0.01 at. %) cause a weakening of the rectifying
aotion of the rectifiers. Copper and niakel were found to cause a decrease
of the rectification ooeffioient. Abdullaye-r and Shapiro (Ref-7, 8) found

vacuum sublimationj in order to eliminate the selenium admixture. However,
thelauthors doubt the need for eliminating the selenium admixture in the
case of semiconductor manufacture. Sublimation in a hydrogen or inert gas
flow is another effective method suggested for purifying tellurium (Ref-71-
T3)'. The sublimation and distillation of tellurium aompolmds, like tetra-
chloride and peroxide, have only a limited signif4cance (Ref.60, 75, 77)-
A high difference in the vapor pressure of the selenium peroxide and the
tellurium peroxide could be used for separating tellurium from selenium ad-
mixtures (Ref.76)- Due to the complexity of the apparatus needed the re-
cently suggested method of tellurium purification.based on the thermal dia-
sociatibn~.of tellurium hydride is unpractical. Besides, the letter method
would give a low yield of the pure product,viz., 24 % and less (Ref-79).
Tellurium is subjected to zonal liquefaction when it is necessary to have
a product of the highest purity. This is necessary for research purposes
(Ref.83). Zonal liquefaction is uneffective in the case of eliminating
selenium and magnesium admixtures (Ref-46, 80). The direct crystallization
