Abstract

Temperature dependence of heat capacity in the range 80-300 K, as well as absolute entropy and standard formation enthalpy, entropy, and Gibbs function at 298.15 K were determined for La(VUO6)3&· 10H2O by reaction and adiabatic vacuum calorimetry. Thermodynamic characteristics of dehydration, synthesis, and solution of the compound were calculated.
