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.
