Thermal Expansion and Other Properties of Sodium Chloride

Abstract

A previous calculation by one of the authors of the equation of state of an anharmonic rigid-ion model of sodium chloride has been corrected. The results are valid above room temperature and reasonable agreement with experiment is obtained to within about 200 0 of the melting point. Comparison with experiment is also made for specific heats C v ' Cp and compressibilities I<T' I<s'
