| Popis: | The heat capacity of TmPO4 in temperature ranges of 9.11–346.05 and 304.6–1344.6 K is measured via adiabatic and differential scanning calorimetry, respectively. The measurement data are used to calculate the temperature dependences of the heat capacity, entropy, change in enthalpy, and reduced Gibbs energy of TmPO4 in the range of 10–1344 K. The Gibbs energy of formation of thulium orthophosphate from elements ΔfG0(298.15 K) is determined. |
