Abstract
Following macroscopic thermodynamic approach and assuming that the product of the volume coefficient of thermal expansion and the bulk modulus is constant at temperatures higher than the Debye temperature it is shown that three parameters, the volume coefficient of thermal expansion, the bulk modulus, and the Anderson-Gruneisen parameter can completely describe the thermo-physical behavior of a solid. The expression derived for the temperature dependence of the bulk modulus was compared to experiments with the conclusion the derived theoretical expression can reproduce the experimental values with high accuracy.
