چکیده انگلیسی
Oxygen potentials of hypo-stoichiometric Lu-doped UO2, (U0.80Lu0.20)O2âx, were experimentally investigated by thermogravimetric analysis using H2O/H2 gas equilibria at 1173, 1273 and 1473Â K. The oxygen potentials of (U,Lu)O2âx were higher than those of other forms of rare earth-doped UO2, specifically (U,Nd)O2âx, (U,Gd)O2âx, and (U,Er)O2âx. Slope analyses for plots of oxygen potential versus deviation from stoichiometry indicated that (U0.80Lu0.20)O2âx had a similar defect structure to that of the other forms of rare earth-doped UO2. A relationship between the effective ionic radii and oxygen potentials was found for the hypo-stoichiometric rare earth-doped UO2.
