Abstract
Abstract Thermodynamic stability of cesium zirconate was determined by measuring the vapour pressure of Cs2O using Knudsen effusion forward collection technique. Cs2ZrO3(s) vaporized incongruently according to the reaction Cs 2 ZrO 3 (s)= ZrO 2 (s)+ Cs 2 O (g) The Gibbs energy of formation of Cs2ZrO3 obtained from the vapour pressure of Cs2O and other auxiliary data could be given by the equation Δ f G° ( Cs 2 ZrO 3 , s) (±18.0 kJ/mol )=−1671.6+0.440T (1142≤T/K≤1273)
