Mg₃(VO₄)₂ powder was synthesized via a simple solid-state reaction under air atmosphere, and X-ray diffraction was employed to investigate the cell parameters of the as-prepared powder. The cell parameters indicated that the sample was crystallized in the form of Cmca orthorhombic system with lattice parameters, a = 6.053 Å, b = 11.442 Å, and c = 8.330 Å. The high-temperature enthalpy changes in Mg₃(VO₄)₂ were measured in the range of 573–1473 K by drop calorimetry for the first time. Furthermore, the temperature dependence of the heat capacity of Mg₃(VO₄)₂ was calculated by considering the enthalpy changes results. Thermodynamic properties (changes in enthalpy, entropy, and Gibbs free energy) were also calculated in the range of 298.15–1473 K.
