•The heat capacity of crystalline phosphate CsCoPO4 was performed between T = (6 and 650) K.•Phase transitions were found at T = (313.40, 486.9 and 514.4) K.•Thermodynamic functions were calculated over the range of T = (0 and 650) K.
The heat capacity measurements of the crystalline phosphate CsCoPO4 with a β-tridymite structure were performed between T = (6 and 650) K. Phase transitions were found at T = (313.40, 486.9 and 514.4) K. They correspond to the polymorphic transformations between two monoclinic and two orthorhombic modifications of CsCoPO4, respectively. Thermodynamic functions Cp,mo/R , Δ0THmo/RT , Δ0TSmo/R and Φmo/R were calculated over the range of T = (0 and 650) K from experimental values and the fractal dimension Dfr evaluated. Standard entropy of formation at T = 298.15 K was estimated to be (−386.40 ± 1.38) J · K−1 · mol−1 for crystalline phosphate CsCoPO4.
