Abstract
CaV2O6 is widely utilized in optoelectronic materials, dielectric ceramics, magnetic candidates, and catalytic materials due to its unique physical and chemical properties. CaV2O6 was synthesized by a conventional solid-state reaction technique in this study. The CaV2O6 crystallizes in a monoclinic system belonging to space group C2/m, with the lattice parameters of a = 10.06 Å, b = 3.675 Å, c = 7.039 Å, and β = 104.843°. The congruent melting of CaV2O6 was detected at 1045 K by performing DSC. Enthalpy increments of CaV2O6 were experimentally measured for temperatures ranging from 573 K to 1023 K employing drop calorimetry for the first time. The temperature dependence of the molar heat capacity of CaV2O6 was then calculated on the basis of the enthalpy increments results. Thermodynamic properties (enthalpy change, entropy, and Gibbs free energy) were also calculated in the temperature range of 300–1000 K.
