摘要：

Oxygen potential measurement on (U,Ce)O//2// minus //x with Ce/U plus Ce ratios of 0. 2 to 0. 5 were carried out at 1073 and 1173 K by a gas equilibration method employing H//2O/H//2 carrier gas. A new wet chemical method based on potentiometric titrations was used to determine and cross check the O/M ratios of the equilibrated samples. Lattice parameters of stoichiometric oxides were determined by x-ray diffraction. The oxygen potentials and their dependence on O/M and composition are discussed and compared with available literature data.
