TITLE: Study of the Effect of-Diffusing Ml-omic Hydrogen on the
Kinetics of Its Electrochemical Evolution
PERIODICAL: Zhurnal fizioheskoy khimii, 1960, Vol. 34, No. 7,
PP. 1508-1516
TEXT: The effect of hydrogen diffusion on the kinetics of its electro-
chemical evolution was studied in Refs. 1-4 using an iron membrane fixed
between two vessels and sealed with vacuum grease. Since a disturbing
effect of the vacuum grease on the overvoltage I was suspected, the authors
repeated their experiments with a new device shown in Fig. 1. A dish made
of Armco iron (2 am in diameter; about 1 am high; wall thickness: 0.1 to
0.07 mm) was connected to a platinum contact by means of an iron clamp.
The outside surface of the dish was polarized,and the inside surface was
exposed to diffusion. Cell I contained hydrogen gas. The dish was filled
from containers 2 and 3 with 1 N NaOH saturated with H2 to a height of
2 to 3 mm. The inside surface of the dish was cathodioally polarized with

the platinum anode 4,'and the diffusion potential Td was measured with
respect to the reference anode.5.As soon as Fd had reached a constant
value, 2 N H2 so4 saturated with H2 and containing traces of Pb(NO 3)2 was
pumped from container 8 into cell I such that it touched the bottom of
the dish. The dish was temporarily polarized anodically. Hydrogen diffu-
sion was discontinued by using hydrogen-saturated NaOH from container 11
instead of the acid solution. These experiments were performed with pure
Armco iron, mercury-poisoned iron, and zinc-platea iron. The results were
in agreement with the ones obtained previously. Overvoltage ~ was increased
on mn-poisoned iron and lowered on Hg-poisoned iron by hydrogen diffusion.
The increase in Ai of the rate of electrochemical hydrogen evolution in
the presence of diffusing atomic hydrogen was determined on Hg-poisoned
iron and zinc-plated iron with ?Z - const. For a given rate of diffusion il,
the amperage i was measured. For Ai/il, the following values were found:

Moreover, the effect of ij., of the cathodic polarization of the electrode,

creased with il and approached a limit. Increase of ~ and decrease of pH

ABSTRACT: After a survey of publications (Refs 1-8) concerning sodium-
-fluoro-beryllate the authors found that the needlelike Na 2BeF4
crystals obtained from an aqueous solution represent an inde-
pendent modification of this compound. They call the latter
6-Na2 BeF 4' The authors,drew this conclusion on the strength of
a thermographic and X-ray investigation. Figure 1 shows the ra-
diogram at 20,360,410,470 and 510 0, figure 2 the heating-thermo-
gram and figure 3 the thermogram of the mentioned modification.

in figure 2, furthermore their irreversibility. The 6-phase can
be considered as an initial phase of a series of polymorphous
varieties formed by it. These latter do not agree with those of
the series C-NYeF 4 (Table 1). The transformation series des-
cribed here is not similar at all to the transformations of

TEXT: The author discusses the structure of monouranates of alkali- and
some bivalent elements. The structure of the uranates is determined by
the type of the uranyl-oxygen lattice groups. Three such types were
found in monouranates: 1. Hexagonal or pseudohexagonal layers of
(U02)02 consisting of (U02)06-cubes which are connected by common
corners; II. tetragonal or paeudotetragonal (UO2)02 layers of (U02)02-
octahedrons which are connected by means of common corners; III.
infinite (UO2)O -chains of octahedrons having some edges in common
(Fig. 1). In ociabedrons and cubes two,U-0-distances are shorter than
CiLrd 1/4

Properties of Uranates
the remaining U-0-distances. The symmetry of the uranate is determined
by the symmetry of the uranyl-oxygen lattice group. A separate range of
the shortest U-U-distances corresponds to each type (Table 1). The
type of the uranyl-oxygen lattice group is rather regularly modified
with the modification of the cation radius (Table 2). This phenomenon is
distinctly exhibited by the uranates of bivalent metals. However, the
modifications with tetragonal or pseudotetragonal layers are known in
all uranates of alkali metals, but other modifications are known only
in Na and Li. The cubic modification of the potassium uranate deviates
from the general structural scheme of the monouranates. The influence
of the cation size on the type of the uranyl-oxygen lattice group is
related with the increase of the coordination number of the cation.
The uranates with a cubic coordination of the oxygen around the
uranium have a smaller molecular volume. The oxygen ions are here more
strongly compressed. Therefore, the smallest distance is short between
the oxygen ions (about 2-5 A in structures of type CaUO 4)' If, e.g. a
part of the oxygen is lost in the reduction of uranates, the compression

mentioned is reduced, resulting in a defective structurd. The di-
uranates of the alkali elements (Ref. 3) also fit into the indicated
structural scheme of the uranates, since they also possess a defective
structure. A positional order of the defects may also take place
without a distortion of the hexagonal call, if a sequence of hexagonal
layers-differing in their structure is assumed (Fig. 1). The uranyl-
oxygen lattice group (U02)0 (Fig. 2) was not observed in any uranate
since it is only found in hitherto poorly investigated polyuranates. The
author proved that the water-oontaining uranates are closely related to
anhydrous uranates with respect to their structure. The reason for the
poor solubility and the difficult meltability of the uranates is to be
found in the absence of distinct uranyl-oxygen ions. The thermal
decomposition of the uranates occurs without destruction of the uranyl-
oxygen lattice group. Therefore decomposition takes place much earlier
than melting. The article under review was read at the 1. VezhvUzovskaya,

TEXT. Using the methods of thermal and X-ray phase analysis, studies
have been made of the reaction of U 308 with Na and K sulfates. The reac-~`_'
tion between U 3 08and Ila2so4begins at 5000C. As a*result of this reactim
sodium di-uranate and UO 2s04 are formed which enter into reaction at a
higher temperature, resulting in the formation of the di-uranate. The re-
action between K 2so4 and U 30., which begins ~t 5800C, is accompanied by
the formation of the potassium tri-uranate and UO 2s0 4' When the tempera-
ture-is raised both these products react'with K 2 so4to form the di-uranatev

TEXT: The authors investigated the reduction of alkali metal ura-
nates with hydrogen. The salts were prepared by baking U 308 with
the corresponding alkali metal carbonates (ratio 1 s 3) and for Li,
by the fusion Of U308 with LiCl,, Reduction was conducted in a tubu-
lar oven. Dried uranates were heated in the current of purified and~'-
dried hydrogen, flowing at the rate of 12 11h. The temperatures of
reduction was increased in steps of 1000C, from 1000 to 12000C, the
reduction process at each temperature continuing for 1 hour. The va-
rious stages of reduction were characterized by changes in weight
and color of the original uranates. The results indicate that the

reduction of the uranates begins at 400 0 - 500 0C, with a rapid lose
of weight at 600 - 80000 due to evaporation of metal hydroxides,~
The final product of reduction is U02o For 14thium, sodium and ce-
sium uranates, U02 is the first product of reduotion. For potassium
uranate KU03 is formed (having a structure of CaT103) as an inter-
mediate phaseq followed by the formation of U02* Similar behaviour
is shown by rubidium. uranate which gives an intermediate phase
RbXU03(x---'l). The author postulate that the process of reduction
proceede by (1) Na2UO4 + H2 = 2NaOH + U02,- Na2U04 + H2 = Na20 + U02
+ H20; 2Na2 0 + H2 = 2NaOH + 2Na*, and (2) K 2 U04 + H2 = 2KUO, + 2KOH;
2K2UO4 + H2 = K 20 + 2KUO3 + H2 0. The reduction of Na, K and Rb di--
uranates was also investigated. The diuranates were prepared by pre-
cipitation from solutions of uranyl nitrates with the corresponding
alkali hydroxideag or by fusion of the alkali metal chlorides with
U 30.. The latter were used for X-ray examinationo Reduction of
Na2U207 begins at 30000. Between 3800 and 4400C various phases are
formed which have similar composition to the original diuranate,

PERIODICAL: Zhurnal fizicheskoy khimii, v. 35, no- 3, 1961, 563-56a
TEXT: The authors produced single crystals of a-Li 2UO4 and P-Na 2UO 41 and
determined the periods of their unit cells. It was not possible to produce
K-, Rb-, and Ca monouranates in the form of single crystals; therefore, they
were studied by the powder method only. The studies were made with Mrl
(RY,OP) and PKA (RKD) X-ray cameras of the NIIF MOU (NIIF MGU (Scientific
Research Institute of Physics of Moscow State University)). a-Li 2U04 single
crystals were obtained by fusing U 306 together with anhydrous lithium
chloride, and P-Na 2U04 single crystals by fusing U 308 with a mixture of
sodium carbonate and sodium chloride. It was found that a-Li 2UO 4and

P-Na2UO 4 crystallized rhombically and had the following lattice parameters:
a-Li2UO 4: a - 6.06; b - 5-13; a - 10-52;
P-Na2UO 4: a - 5.971 b = 5.795; o - 11.68. Potassium-, rubidium-, and
cesium monouranates belong to the structural type K2 NiF4 (tetragonally body-
centered), P-Na 2UO4 may be regarded as a rhombically distorted K 2NiF4 struc-
ture. The authors discussed the arrangement of alkali metals in monouranate
single crystals. The uranyl oxide lattice of P-Na 2U04 is maintained in
a-Li2IJO 4' but a different arrangement of alkali metal atoms is more likely
in a-L12UO 4* The structures of lithium, sodium, and potassium monouranates
determined are not identical with those indicated by W. H. Zachariasen
(Ref. 4: Manch. Pr. Report CP-2611, p. W., The authors explain this dis-
agreement with the polymorphous properties of uranates. There are 3 tables

TITLE- Double oxides in the system uranium - tungsten - oxygen
PERIODICAL: Akademiya nauk SSSR. Doklady, v,. 141, no. 1, 1961, 114-116
TEXT: The authors investigated oxides formed by interaction of uranium
and tungsten oxides, as well as by thermal decomposition and reduction of
uranyl tungstate by hydrogen. They used H 2WO 4 and (UO2 )NO3 (chemically
pure, for analysis) as initial substances from which they produced WO 29 W9
DO 21 U3 0., and DO 3' An PKA-57(RKD-57) camera was used for the X-ray phase
analysis. Samples in the system DO 3 - WO3were produced from aqueous
suspensions of H 2W04 and DO 2( OH )2 by prolonged boiling, subsequent evaporat-
ing, and 45 hr roasting at 900 00. It was found that only one compound,
UO2WO 4# was formed in the system UO 3 - WO 3' Uranyl chromate and molybdate
were synthesized for comparison. The X-ray patterns of the three compouncJs

very similar, which speaks in favor of their isostructure. Uranium and
tungsten oxides of lower valencies were produced from UO 2Wo41 by thermal
0
decomposition in vacuo at 600 - goo C, by reduction of uranyl tungstate at
300 - BOOOC, and by sintering various uranium and tungsten oxides in
evacuated ampuls at 1250 and 900 0C (Table 1). Two new phases appeared in
these oxides. One was similar in structure to U 30a and corresponded to
U-Wo 5+x* An analogous phase was obtained by thermal decomposition of UO 2Wo4
in vacuo at 800 0C (total formula UVIO 5.5) and at 9000C (UWO 5.01 )~ The other
phase showed a Debye powder pattern with cubic syngony, parameter of the
primitive elementary cell a = 3.805�0.001 kX~ This compound was synthesized
by sintering UO 2 and WO3 at ratios 1:1 and 1:10. At ratios 1:25 and 1t50,
the cubic cell was tetragonally distorted. When sintering WO 3 and WO 2 at
ratios 15:1, 25:1, and 50.1, no cubic phase was formed, and the cell was
rhombically distorted. Consequently, thecubic phase only forms in the
presence of U. It is similar to WO 3 but probably contains less oxygen,
((W,U)03-x). The sample of UO 2 + lowo 3 contains a phase of the UO 2 type

which probably contains some W; a - 5.461+0.001 kX. The cubic phase is not
yet formed in the sample of UO 2 + 25WO 3 *Conclusions: The ratio U:W, in the
cubic phase lies close to 1:15-20, x A 1/15-1/20. At higher temperature
(above 12500C), the phase UWO 5+x disproportionates. Up to 12500C, there is
no interac.tion between UO 2 and WO 2' In sintering, the lattice parameters of
the initial phases do not change, i. e., no solid solutions are.apparently
