Abstract

Cerium orthovanadate has been prepared by solid-state reaction via multistep firing of a stoichiometric mixture of CeO2 and V2O5 in the range 873–1273 K. The molar heat capacity of CeVO4 has been determined by differential scanning calorimetry in the temperature range 350–1000 K. The experimental data have been used to evaluate the thermodynamic properties of cerium orthovanadate: enthalpy increment H°(T)–H°(350 K), entropy change S°(T)–S°(350 K), and reduced Gibbs energy Φ°(T).
