Because of the very low conductivity of fused beryllium chlorid
a direct measurement of er.df. could not be madev and for this
reason the investigation described was limited to measuring the
e,M',f. of cells with chlorine and carbon-dioxide electrodes of
beryllium in fused equimolar mixtures of sodium and potassium
chlorides, containing from 0'.064 to 7.35 wt'. % BeC12- It was
found that the e'.m.f. of this cell changes witb temperature

melt, Carbondioxide electrodes of beryllium were found to be
reversible with respect to its ions in chloride melts. At low
BeC12 concentrations the melts behave like ideal solutions.
From the eiperimental data and those obtained in the literature
the change in the isobaric potential on transition from pure
liquid BeC14 to its dilute solutions in melted eutectic mix-
ture of sodium chloride and potassium chloride was calculated
to be 229400 - 39'.53 T cal'. per mol. BeCl Mixing the fused
salts was found to be endothermic and to ?; accompanied by in-

PERIODICAL: Izv. Vost. fil. AN SSSR, 1957, Nr 3, pp 94- 101
ABSTRACT: On the basis of experimental data on the electrolysis of
fluoride/chloride melts containing Ti4+ it was shown that the effect
of the atmospheric 02 within them and the suspended insoluble
dioxid2 led to the formation of oxy-cations of the TiOZ + and
Ti203 + type, which when discharged at the cathode yield well
formed crystalline precipitates of the lowest Ti oxides. These
oxide;s were precipitated with potentials 1.3 - 1.4 volts more posi-
tive Vaan the potential used to segregate metallic Ti, and 2.2 - 2.3
volts more positive than the potential used to segregate an alkali
metal. Tests were made to clarify the nature of the processes
which take place at the cathode and at a carbon anode when electro-
lysis occurs with small current densities. It was found that the

actions involving the particles of Ti02 -Ti203, and TiO suspended
in the melt were also possible. The anode potential during these
processes was r\j 0.4 volts more negative than the potential of a

ABSTRACT: In the electrolysis of fused chloride baths C02 is separated on the
anodes prepared from an intimate mixture of oxides and carbon and the
ions of the corresponding metals pass into the electrolyte. The oxide-
carbon electrodes of thorium, calcium, beryllium, etc. in equilibrium
are reversible in relation to their ions being in the electrolyte.
This permits -to utilize them by the emf-method for elucidating the
thermodynamics of reactions, in which oxides and carbon take part at
high temperatures. The equilibrium potentials of the electrodes are
determined by the activity of the Ions of the corresponding metals in
the electrolyte and by the CO pressure over them according to the

ABSTRACT: A method of preparation has been described and results are cited of
measurements of the electric conductivity of solid electrolytes for fur;'-
elements: a) O.K. Davtyan's eleotrolyte and its individual components
(Na2C03, calcined monazite); b) a series of mixtures of oxides on the
base of zirconium dioxide: 60 molar % ZrO2 + 40 molar % CeO2; 67.7
molar % Zr02 + 33.3 molar % La203; 3ZrO2 - 2CeO2 + 10 weight % CaO. Tbe
measurements of electric conductivity were carried out by tne impedance-
bridge method at a frequency.of 1,000 cycles. The circuit permitted the
determination of the resistance with an accuracy of 1 - 10%, depending,
on the value of the measured resistance. The conductivity was measured

ABSTRACT: The temperature denpendence of the electrical conductivity (d ) of
polycrystalline samples of NiO and Cr 0 sintered at 1,5500C, was
studied in the interval of 150 to 900 gC311 (Swas measured by means of
the contact method with the aid of an alternating current bridge at a
frequency of I kc. Contact resistances did not affect the temperature
dependence of 6 . It was established that (5 for NiO, unlike Cr 203, in-
creases sharply with an increase in the quantity of adsorbed oxygen,
while the activation energy of the conductivity of NiO, measured on
rectilinear sections, decreases. In the case of Cr2o the activation
energy of 6 falls with an increase in temperature. & absence of Ionic
conductivity under the conditions of the experiment was established by
means of a chemical analysis of the areas near the electrodes.

ABSTRACT: This is a report on the structure and the ceramic properties
of the s;fstem Ce02-ZrO The samples were prepared from mix-
K
tures of pure oxides.
e spectroscopically determined content
of impurities in the initial substances is given in table 1.
The powders were pressed, a binding agent (natural rubber
in benzene) being used for samples with more than 800/L Zr02. The
samples-nere then sintered and X-ray investigated with copper
K -radiation (powder camera of type RKD and inverting camera

(Fig 2) in sintering were determined. Table 2 gives the che-
mical composition, the phase composition, the lattice constants,
and the color of the samples. A solid solution with cubic
lattice develops between 0 and 50 mol% Zr02, a monoclinic

distributed lattice defects which are probably situated in
the lattice points occupied by the Ce4+- and 02--ions, The
samples with 70 mOl% Zr02 have the greatest hardness; linear
shrinking exhibits a minimum at 20-25 mol% ZrO ; the samples
with 10-20 mold.' Zr02 are most intensely coloreq. A vigorous
interaction between the two components seems to take place in
this range (between 10 and 30 mol% Zr02). This interaction
cannot be determined by X-ray investigation, it should, how-
ever, become manifr.Az~t in the electric properties. There are
2 figures, 4 tablEs, and 3 references.

TEXT: The authors studied the temperature dependences of the conductivities
of 100% ZrO 2 - 1006 CaO samples between 300 and 1000 0C, the transfer
numbers, the structural properties of sintered samples and their ceramic

For samples with< 40 mole/i CaO the authorn uned CaO, for those with >40010
CaO, they used CaCO 3' The mixture (200 mesh grain size) was pressed to
1 0.1 0-062 - 0.4 cm tablets at -4000 kg/CM2 , and sintered for 1 hr at
1;00 - 20 C. Linear shrinkage during sintering, properties, and color
were determined. G. V. Burov made X-ray structural analysis of the

specimens with Culla, radiation. At 15000C, solid solutions and fluorite-
type crystal lattices formed with 10 mole% Cao. The primary solid solution
(10.0 - 40.0 mole% CaO) yields good ceramics of high density, hardness,
and stability in air. Free CaO contained in samples with 80.0 - 90.0 mole%
CaO reacted with atmospheric humidity. The porosity and sample volume of
zirconate formed according to ZrO2 + CaO ----,CaZrO3increases while its
linear shrinkage decreases. The temperature dependences of conductivities
measured with a-c bridges followed the equation x = A exp (-41/2kT) where
is the conductivity, A and AE are constants. At 750 - 800 C, the curve
showed a break (except for the range where solid solutions are formed).
X-ray patterns of samples with>50 mole% CaO showed CaO lines. x was
increased by the formation of Ca(OH )2 and CaO3and decreased by their
decomposition (700 - 8000C). The rapid increase of x with the CaO contt-nt
in the range of formation of solid solutions is probably due to an increase
in oxygen vacancies in the lattice. With increased CaO content, the defects
are no longer distributed statistically but systematically. The mobility
of oxygen ions is thus reduced. With 15 mole% CaO, the conductivity
maximum was observed at the minimum conductivity activation energyA E. The
Card 2/4

increase of linear shrinkage with the number of vacancies is probably due
to the existence of oxygen vacancies only. CaZrO 3 had a x minimum and a
AE maximum. The second, smaller x maximum at 60% CaO is probably due to
the formation of the CaZrO - CaO eutectio. Another small x minimum was
3
observed at 90% Cao. The transfer number wAs determined from the weight
losses. Three oxide plates 3 - 4 mm thick and 20 mm in diameter were
used as catholyte, central piece, and anolyte Theyowere ground on each
other, pressed between Pt electrodes, heated ;o 1000 C, and electrolyzed
at 0.02 - 0.03.a for 2 - 4 hr. The transfer number was calculated as-
follows: t - (Aa-1.19)/AB and t (Ak-1.19)/AB, where t and t are

the transfer numbers of cation and anion, respectivelyoA a and 6k are the
weight losses of anolyte and catholyte, respectively, A is the eleotro-

to Table 2, t k was 4-0.01, ta was,,&E 1,

the conductivity maximum, with 5 - 40 mole% Caot the samples can easily
be sintered, are of great mechanical strength, low porosity, and 'nave no
cracks. An increase in conductivity with increasing CaO content (4 5-10
mole';4,) in accompanied by increased linear shrinkage. The conductivity
minimum caused by interaction of the components lies at 50 mole% CaO.
Then, the conductivity increases and remains constant between 55 and 75
mole% CaO. These samples have good--ceramic properties and a weak color.
The rapid decrease in conductivity at,100 mole% CaO (white samples with
poor ceramic properties) is obviously caused by large amounts of
non-reacting CaO and ThO The change in the conductivity activation
energy corresponds exacti~ to the change of the conduction isotherms.

increases, i.e., it becomes hole-type. Moreover, this relationship is somewhat
stronger in a system containing BaO than in a system with SrO. In the Hf02_8e0
system, neither a solid solution nor a chemical compound is formed, and the iater-
action of the components Ls not reflected in the magnitude and nature of the con-
ductivity. Orig. art. hais: 10 figures, 9 tables and I formula.

varying amounts; addition of CaO of up to 40 mole% resulted in the
formation of solid solutions. The preparation ef the samples was already
described in Ref. 1. The relative electron and ion conductivities were
determin8d by the 0solid electrolyte emf method at temperatures ranging
from 500 to 1000 C, and herefrom the activation energy was computed.
It was found that ion conductivity increases with an increase in tempera-

to ion conductivity. This effect was not observed in the systems
CeO 2 -CaO ard ZrO 2 -CaO. The authors give the following explanation:

As a result of partial reduction of Ce to Ce , first an intense ele.-
tron conductivity occurs in the system Ce02 '- Zr02' Increasing addition ux
of CaO inhibits this reduction more and more, and the ion conductivity
caused by oxygen ions takes the place of electron conductivity, A decrease
of conductivity in samples containing over 40 mole% CaO is attributed to
the accumulation of free CaO not converted into a solid solution. There

In-ta elektrokhimii Urallskogo filiala AN SSSR, vyp. 1, 119 (1960); ibid.

ductivity method can be used to detect the formation of chemical com-
pounds. Thus, for CaZr02, SrZrO,o 3aZrO,l SrCeO 31 and BaCeO 39 low minima'JI/

the 8ec*ond kind with imperfect crystal lattice (vacancies in the anion
sublattice). The number of vacancies grows with dioxide concentration.
Conductivity grows with the number of vacancies until they react with one
another. The conductivity peaks of ZrO 2-MgO; ZrO 2-CaO; CeO 2-MgO;
CeO 2- CaO; CeO 2-SrO; CeO 2-ZrO 2- CaO with 15 - 25 molesl/:~ MeO are dependent on
this. In the ZrO 2-MgO system besides the cubic, a monoclinicsolid-solution
(0-4 moles~3~ MgO) was found by electrical conductivity. In ZrO -CaO, a
2
solid solution of monoclinic ZrO 2 was found with low CsO concentration.
In ZrO 2-CeO 27 the electrical conductivity minimum is determined by the
semiconductor properties of the oxides in the solid solution. In
Ceo 2- ZrO 2- CaO, with 8 moles/a CaO, the minimum is related to the trarisi-
tion from electron to ionic conductivity. The capacity for chemical
interaction, reduction, and the type of phase are revealed as extreme
values on the electrical conductivity - composition isotherms. Their
interpretation, together with that of sintering shrinkage, can be used to
reveal the very faintest physical properties of the oxides examined.

ABSTRACT: The structural components of the Zr02-PrO1.83 system were studied in samples
obtained by sintering powder mixtures of the two oxides. the phase composition of the producV
was studied by x-ray diffraction and chemical analyses. In all samples, a phase with a fluorite
structure was present. In mixtures of equimolar composition, another phase designated by X
was also present. The reaction products behave differently toward hydrochloric acid: the
solubility to low in the region adjacent to the original ZrO2, and high (almost complete) its
PrOl. 83 is approached. The boundary of zero solubility Is the equimolar composition. The
chemical compound X was insoluble In HC1. In comparing the x-ray and chemical analynes,
the authors found It difficult to arrive at a general interpretation of the data: on the one hand,

broad regions of solid solutionei with a fluorite-type structure were observed, the nature of the

formation of which varies; on the other hand, the characterof the distribution of the reacting
ioxides is apparently related to the presence of a large number of phases in the reaction
products. Orig. art. has: 2 figureo and 3 tables,
