Melting Temperature of MgO under Pressure

Article Preview

Abstract:

The melting temperature-pressure phase diagram [Tm(P)-P] for magnesium oxide (MgO) is predicted through the Clapeyron equation where the pressure-dependent volume difference is modeled by introducing the effect of surface stress induced pressure. MgO is a material of key importance to earth sciences and solid-state physics: it is one of the most abundant minerals in the Earth and a prototype material for a large group of ionic oxides.
