摘要：

The change in stoichiometry of solid solutions of U//0//. //7//7Pu//0//. //2//3 and U//0//. //8//5 Pu//0//. //1//5 oxides with oxygen potential between 1523 and 1823K has been determined. A thermogravimetric technique was used to establish the equilibrium between the oxide phases and CO/CO//2 gas mixtures of known oxygen potential. Particular attention was given to the relationship between the stoichiometry and the oxygen potential in the region very close to the stoichiometry composition. New data have been obtained for oxides with O/M ratios 1. 9984-2. 0000.
