Synthesis and study of the heat capacity of orthovanadate TbVO4 in the range 5–859 K

详细

The heat capacity of TbVO₄ has been measured by the adiabatic calorimetry (5–346 K) and differential scanning calorimetry (344–859 K) methods. The C_p = 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.
