Equation of State for Molten Alkali Halides by Thermodynamic Perturbation Theory.

Several variants of the equation of state (EoS) for molten alkali halides are considered using the thermodynamic perturbation theory. Most attention is focused on taking into account the charge-induced dipole (or induction) term to pressure. The model of charged hard spheres of different diameters within the mean spherical approximation is used as a reference system.
