Oxygen potentials of (Th$$_{0.7}$$Ce$$_{0.3}$$)O$$_{2-x}$$ were experimentally determined by means of thermogravimetric analysis as a function of non-stoichiometry at 1173 and 1273 K. Oxygen potentials of (Th$$_{0.7}$$Ce$$_{0.3}$$)O$$_{2-x}$$ at each temperature increased with increase of O/M ratio (= 2-x) and steep increases of the oxygen potentials toward O/M = 2 were observed. These characteristics are typical for non-stoichiometric fluorite-type actinides dioxides. The oxygen potentials of (Th$$_{0.7}$$Ce$$_{0.3}$$)O$$_{2-x}$$ were similar to those of CeOO$$_{2-x}$$ when they were plotted as a function of average Ce valence.
