Abstract: The data on the molar heat capacity of GdVO$_4$ and SmVO$_4$ as a function of the temperature have been obtained. The thermodynamic properties of the oxide compounds have been calculated from the experimental data. It has been shown that the specific heat capacity of La–Gd oxides and their orthovanadates change regularly depending on the ionic radius R$^{3+}$ within the first and second tetrads (La–Nd, Pm–Gd). The values of $C_p^0$ (298 K) have been evaluated for PmVO$_4$ and CeVO$_4$.
