Abstract
The heat capacity of TbVO4 has been measured by the adiabatic calorimetry (5–346 K) and differential scanning calorimetry (344–859 K) methods. The Cp = f(T) plot has an extreme point (32 K). The thermodynamic properties of the oxide compounds have been calculated from the experimental data. A general equation that describes the heat capacity of terbium orthovanadate as a function of temperature in the range 35–859 K has been derived.
