ABSTRACT: The formation of fluorite-type phases was investigated in R203-U308-0 SYS-1
tems (where R=La, Sm, Dy, Yb) annealed for 66-85 hr at 12000C, and the solubility
limits of the rare earth oxides in urani octoxide were deter-minnd. The U(V1) con-
tent and the total uranium content were termined by coulometric analysis at a con-
trolled potential. X-ray phase analysisiftas carried out by using the powder method
with RKD-516d RKU-86 ameras.\t4 e egree of oxidation of uranium changes with the I
ratio R/U a~d rei~_h_es 6 in snmples where R/U=2/1. Thus, the presence of a rare earth
oxide increases the stability of the hexavalent state of uranium at high temperatures.1
Contrary to expectations, the solubility of rare earth oxides in U308 was found to be
very low (less than 1.S mol % of ROI.5). Orig. art. has: 3 tables.

ABSTRACT: The interaction of rare earth oxides R203 (R = La, Sm, Ey, Yb) with UO~ and
the solubility of the latter in the rare earth oxides "were studied by x-ray phase an
Ysis. In R?0 6 -
3tUG3 systems with R,20~ >50 mole %, the existence of three phases wa
established: a cubic solid solutior~ with a fluorite structure, and U%012 *~ nd R,2_~-tyw
compounds. In lanthanum and samarlum in the range U03;R20j = 1 -*1.25-1.,1.75,, *an ther
phase was found which like UR601? has a rhombohedral lattice. The binary oxides
UR6012 have the structure of Tb7012. The indexing of x-ray patterns of the oxides
UR6012 'is tabulated. In the La2O,3-U3% systemp another rhombohedral phase was observed
up to 11000C; its composition Is 21a2 %with sublattice parameters (in the hexag-

TITLE: New double oxides of niobium
SOURCE: Moscow. Universitet. Vestnik. Seriya II. Khimiya, no. 3, 1966, 89-90
TOPIC TAGS: niobium compound, niobium double oxide, aluminum compound, iron
compound, chromium compound
ABSTRACT:. A study of double oxides which could be formed in the systems:
Al 0 Nb 0,-, Fe 0 - Nb 0 or Cr203 - NbZO~ was prompted by previous information
2 3- 2 2 3 2 5
on the existence and composition of some double oxides. The above systems were
investigated in areas rich in niobium. Ilie following compounds were obtained;
A120 -llNb 0 and Fe203-llNb20 isostructural to the monoclinic and rbombic
modilicatio'ns' of T12Nb10O29, ana'double oxides Me203-49Nb20 , where Ile is'either
Fe or Cr, and which are isostructural to Z102-7Nb2O5. The iattice constants were
determined an.-I given in the original in tabulated form. The results indicate that
the conclusions obtained by H. J. Goldschmidt on the existence of solid solutions
in the systems Me 0 - Nb 0 (Me Al; Fe; or Cr) are incorrect. Orig. art. has:

AI~STRACT: The solid solutions U308-R 203 (11 - Li, Sm, Dy',-8-nd Yb) co-.-,tain'Jn:; up to-
50 mole ~ of uranium oxides were subjected to the action of oxygen in an 3utoclav
at a pressure of 230 atmospheres and a temperature a 6500 for 100 hours. The ex-
of oxidation of uranium was deterrained gr3vimetric3lly by chance in weiGht,
illed cathode potential. The systematic dif erenec
.and coulometrically with a contro L. U ff
in an&lyses between gravimetric and coulometric methods is apparently due to the
partial adsorption.of oxygen and water vapor. A comparison of the data of the
coulometric analysis prior to oxidation vith oxygen and after, shows that single-
