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_fG⁰(298.15 K) is evaluated at 1851.8 ± 4.7 kJ mol^–1.
