摘要：

The temperature dependence of the heat capacity of crystalline nickel zirconium phosphate C-p(circle) = f(T) was measured over the temperature range 6-664 K. The experimental data obtained were used to calculate the standard thermodynamic functions of Ni0.5Zr2(PO4)(3) from T -> 0 to 664 K. The standard entropy of phosphate formation from simple substances at 298.15 K was calculated from the absolute entropy of the compound. The data on the low-temperature heat capacity were used to determine the fractal dimension of Ni0.5Zr2(PO4)(3) over the temperature range 30-50 K. Conclusions concerning the heterodynamic characteristics of the structure of Ni0.5Zr2(PO4)(3) were drawn.
