Melting Temperatures of Several Oxides under Pressure


Article Preview

The melting temperature-pressure phase diagram [Tm(P)-P] for corundum (Al2O3), wustite (FeO) and magnesium oxide (MgO) are predicted through the Clapeyron equation where the pressure-dependent volume difference is modeled by introducing the effect of surface stress induced pressure. The model prediction is found to be consistent with the present experimental results.
