• Elastic properties
• thermal expansion

We derived new expressions for volume expansion ratio, thermal expansivity and higher order temperature derivative of volume with the change in temperature. The relationships are developed on the basis of suggestion made by Wang and Reeber [12]. We used a relationship demonstrating the temperature dependence of isothermal bulk modulus due to Srivastava et al. [13] to generate various other expressions. The model is applied on NaCl and KCl crystals. The superiority of the presented formulations over other identical formulations is shown. A close agreement between theory and experiment reveals the validity of the present work.
