Contribution

It introduces a semi-classical approach combining Coulomb interactions and experimental rules for calculating phase transition pressures in solids.

Findings

Applicable to diamond anvil cell experiments

Used for planetary structure modeling

Based on Coulomb interaction and experimental postulates

Abstract

This is a short review of the physical ideas,algorithm for the calculation of the phase transition pressure and some results of a semi-classical theory of the behaviour of materials under high pressure proposed by P.Savic and R.Kasanin.It is base on the Coulomb interaction,supplemented by a microscopic selection rule and a set of experimentally founded postulates,and it has found applications from DAC experiments to planetary structure modelling.
