Low-temperature heat capacity and thermodynamic properties of PrPO4

The heat capacity of praseodymium orthophosphate PrPO4 was measured by adiabatic and relaxation calorimetric techniques at 5.12–345.54 K, and these data were utilized to calculate thermodynamic functions of PrPO4 at 6–350 K. The Gibbs free energy of PrPO4 formation Δ f G 0(298.15 K) is evaluated at 1851.8 ± 4.7 kJ mol–1.
