The Equation of State of Sodium Fluoride

Abstract

The equation of state of Sodium Fluoride is studied by the method of Verma and Dayal. Theoretical values of thermal expansion are compared with the experimentally measured values and a satisfactory agreement is found upto 530 °K. The theoretical values increase progressively above this temperature. It seems that the parameter ∂ in the exponential interaction term is a function of interatomic distance.
