✦ Synopsis

A new interionic potential has been used to study the variation of heat capacity at constant volume. heat capacity at constant pressure and coefficient of volume expansion with prcssurc at room temperature.

A classical theory of lattice vibrations.

originally proposed fo!-crystals under zero pressure, has been extended to calculate these thermal properties at higher pressures.

These calculated values have been compared with the theoretical estimates obtained using a deformable dipole model of ionic solids. Values of heat capacity at constant volume have also been compared with experimental values.
