Abstract

A semiempirical model equation of state is developed in terms of bulk modulus and the Grüneisen parameter to compute the melting temperature of sodium in the gigapascal range of pressure. The model successfully explains the increase and decrease of T m as the pressure increases. Computed values of the critical pressure and temperature are in very good agreement with the experimental observations.
