Abstract :
The thermodynamic stability of cesium thorate, prepared by the sol–gel method following the citrate–nitrate route, was determined by measuring the vapor pressure of Cs2O by the Knudsen effusion collection technique. Cs2ThO3(s) vaporized incongruently according to the reaction Cs2ThO3(s)=ThO2(s)+Cs2O(g). The Gibbs energy of formation of Cs2ThO3 derived from the measured vapor pressure of Cs2O and other auxiliary data could be given by the equation ΔfG°(Cs2ThO3,s)(±20 kJ/mol)=−1780.1+0.437T (1100⩽T/K⩽1254).
