Abstract: A simple theoretical method is used to investigate the properties of solids under varying conditions of temperature and pressure. The case of NaCI is discussed as an example for the entire range of temperature and pressure, viz. from room temperature up to the melting temperature (1000 K) at the pressures varying from atmospheric pressure (referred as P = 0) up to the structural transition pressure (P = 30 GPa). The results obtained for the temperature dependence of thermal expansivity are compared with those based on the widely used Suzuki equation. The results of the pressure dependence of thermal expansivity are compared with Anderson-Masuda relation. The results of Wang and Reeber [Phys Chem Miner, 23 (1996) 354] are also included for the sake of comparison. The good agreement with the available theoretical as well as experimental data, supports the simple method used in the present paper.
