Heat Capacity and Thermodynamic Properties of La3TaO7
The molar heat capacity of lanthanum tantalate La3TaO7 of the weberite structural type was measured by the relaxation, adiabatic, and differential scanning calorimetry methods in the temperature range of 0–1860 K; the thermodynamic properties: entropy and enthalpy increment were calculated from the smoothed values of heat capacity; the Gibbs energy of formation of lanthanum tantalate from binary oxides in the high-temperature region was estimated; and La3TaO7 was shown to have high stability.
