Abstract
The molar heat capacity of the solid solution Tm2O3‧2HfO2 has been determined for the first time by relaxation, adiabatic and differential scanning calorimetry, the temperature dependences of entropy and enthalpy increment in the temperature region 0–1800 K have been calculated, and the contribution to the heat capacity of the Schottky anomaly at 0–300 K has been evaluated.
