ABSTRACT: The investigation of the equilibrium of the nickel tungstate
with hydugen was carried out, completed by a radiographic in-
vestigation of its reconstruction goducts. The equilibrium
constants of the reconstruction of NiTIO 4 by hydrogen were
meagured at four temDeratres within the region of from 806 -
990 C. It is shown that the reconstruction of NiWO by hydro-
i

gen takes place on three stages. The final product

are given here. The specific heat was determined according to the
method for mixing in a massive calorimeter. The description of

TEXT: The present paper is a report\on the continuation of investigations con-
cerning the thermodynamic propertiesf~bf the tungstates and molybdates of bivalent
metals. The mean specific heats of Ca-, Mn-, and Co-tungstate were determined in
a calorimeter at 573 to 10730K. The working method and apparatus have already beek~_
described (Refs. 2 and 5). The measurement values are given in a table. A poly-
morphous transformation was found to take place in CoWO 4 within the temperature
range of 973-1000 0K1 in this case the heat of transformation was found to be
145 Gal/mole. Equations for the mean and true specific heats of the tungstates
under investigation are given. By means of the equation of the true molar specific
heat, C. - 26.1o + 0.0126 T, the specific heats of tungstates and solybdates of

TEXT: The present work follows a series of experiments on the thermo-
dynamic properties of the chromates, molybdates, and tungstates of di-
valent metals (Refs. 1-4). Its principal purpose was to compare the thermo-
dynamic properties of these compounds with those of the uranates of di-
valent metals. The mixing method was used to measure the specific heat of
CaUO and BaUO with a compact calorimeter. The measurements were made
betwien 5880 a
wid 11340K, the lower temperature being 2930K. A detailed
description of measurement and calorimeter is given in M. M. Popov's
manual (Ref. 8) and in a paper by L. A. Zharkova and T. N. Rezukhina
(Ref. 2), The sample was heated in a Pt ampoule placed in a vertical fur-
nace above the calorimeter. The soecific heat was calculated from the

difference of the quantities of h-~at introduced into the calorimeter with
a full and with an empty ampoule. The mean values obtained are listed
in Table 2. The specific heat of BaUO 4 in the above temperature range
was found to be a linear function of temperature. In the case of CaUO
this function is linear only up to 1022 0K, changes abruptly between 4
1022 a and 1027 0 K, and becomes again linear. In this range there occurs a
phase transition with a heat of 220 cal/mole. Finally, equations are
given for the calculation of the mean and the actual specific heat for the
temperature range considered: CaUO 4 (1) (below the point of transition):

PERIODICAL- Zhurnal fizicheskoy khimii, 1960~ Vol, 34., No. 9, p., 2129
TEXT-. For the purpose of determining the formation enthalpylof Ce 2039
the reaction heat of the reaction Ce 203 1/2 0 2 = 2 Ceo2 was determined
The Ce 203 was obtained by reduction of CeO 2 in a hydrogen current at
12510-13000C. The reaction heat of this reaction was determined by the
diathermic method by means of a calorimeter (volume of the bomb, 0,04 1)?
and the exDerimental results of Ce 2 03 combustion are given in a table.
After the necessary corrections had been made, the value-'H 0
298.2
-85-43 1 0.26 kcal/mole was obtained for the reaction, and, according
to (Ref, 3), AHO 260.16 � 0.33 kcal/mole is substituted for the

TEXT: As published data concerning the reduction of niobium oxides are
insufficient, and the equilibrium of low niobium oxides with hydrogen has
not yet beeen studied at all, the authors report on the reduction of
Nb205 in equilibrium with H2 to NbO, as well as on the measurement of amf
of a galvanic cell of 1FoO and metallic niobium. The equilibrium of
niobium oxides with hydrogen between 1200 and 15500C was studied in. a
circulation apparatus described in Ref. 8. The samples were placed in a
molybdenum furnace on a platinum base in such a manper that they touched
the Pt in a few places only, and were reduced in a hydrogen flow. The
total com-position of the reaction products was determined from the

ABSTRACT: The article describes the use of the electromotive force
method using a solid electrolyte to measure the properties of the above
mentioned compounds. The measurements were made on apparatus described
elsewhere in the literature (citations given). Most of the measurements
were made in an atmosphere of inert gas, and some in a vacuum. The
experimental results are shown in graphic and tabular form. The data is
used to calculate the thermodynamic properties of mono- and trIcalclum
tungstate and tribarium tungstate. In the temperature Interval from
1200-15900K, measurememts were made of the electromotive force of cells
with a solid O-electrolyte, containing tribarium and tribarium tungetate.-I

':ABSTRACT- A cell was designed for electrochemical measurements in oxide systems at'~
'high temperatures (see fig. 1 of the Enclosure). The emf of galvanic cells with
;solid electrolyte was me'asured up to 16000K., To check the p erformance of the appa-i
~ratus the emf of cells containing iron oxides, as well as iron and cobalt chro
i mites
!was used. The emf of the following cell was measured in the 1300-15500K tempera-,

IThe thermodynamic functions for NiCr204 were obtained for the first tire and com-
ipared to iron and cobalt chromites. The high negative value of the isobaric poten-!-
itial is characteristic for the formation of all three cbromites from oxides. en
Ev
lat high temperatures (1200-15009C), these chromites are stable with respect to or-
dinary reduci ng agents
(CO and H2).' Therefore, during reduction melting the pre-
sence of chromium in oxidized cobalt-nickel ores would lead to the loss of cobalt
and nickel with the-slag. Orig. art. has:.

TEXT; The gallium and antimony employed was 99,99% pure
(zonal veerystallization) and the compound GaSb was obtained by
heating a stoichiometric combination of Ga and Sb in evacuated
quartz ampoules, followed by structural X-ray analysis, It is
stated that there is no published information about the specific
heat of GaSb, The specific heats of the above substances were
measured by the method of mixtures in a massive calorimeter in the

The discrepancy is ascribed to the fact that Schubel did not take
into account the cooling of the specimen as it drops from the
furnace into the calorimeter. Ifeat losses by evaporation of the
calorimetric liquid were not corrected for by Schubel.

TEXT: The authors determined thermodynamical data on cerium which,

Ce2OV and obtained the value AHO 298 ~_85.43 kcal. The present paper deals
with the thermodynamical properties of cerium oxides in the CeO 2- CeO 1-5
range of compositions. They used the emf method with a solid electrolyte
(Ref. 7, see below). In addition, the authors measured the equilibrium
constants of cerium oxides with hydrogen. They used a more convenient

Mixed crystals of the system ThO 2-La 203with a purely ionic conductivity

mixture2of corresponding amounts of Ce02 and Ce2o 3 at a pressure of
10 t/cm . The oxygen content of the preparation was determined by
measuring the emf by the method of "active oxygen". CeO x was handled in
an argon atmosphere. The values of the equilibrium emf of cell correspond
