Study Of Equation of State for Some Ionic Crystals

Abstract

An equation of state (EOS) is a fundamental framework in thermodynamics that expresses the relationship between the key thermodynamic variables that describe a system, such as pressure, volume, and temperature. We are utilizing an isothermal equation of state (EOS) to investigate the correlation between pressure (P) and volume compression under a specific temperature and also employed to examine the isothermal bulk modulus (B_T) and its pressure derivatives (B_T’) and Gruneisen Parameter. This study delves into the analysis of the equation of state applied to an ionic crystal. In the present paper we have used 3 different, (I) Birch – Murnaghan EOS, (II) Vinet – Rydberg EOS, and (III) Brennan – Stacey EOS for Na-Cl which are Sodium Halide of ionic crystals. The comparison reveals that the all EOS yield very similar results.
