摘要：
The temperature dependence of the heat capacity of crystalline Sr0.5Zr2(PO4)3 phosphate was studied by precision adiabatic vacuum and dynamic scanning calorimetry over the temperature range 7–665 K. The low-temperature dependence of the heat capacity was analyzed using the Debye theory of the heat capacity of solids and its multifractal generalization, which allowed conclusions to be drawn about the heterodynamic characteristics of the structure. The experimental data obtained were used to calculate the standard thermodynamic functions of Sr0.5Zr2(PO4)3 from T → 0 to 665 K. The standard absolute entropy of Sr0.5Zr2(PO4)3 was in turn used to calculate the standard entropy of its formation from simple substances at 298.15 K.
