Melting Temperature and Shear Modulus of MgO under High Pressure

Melting Temperature and Shear Modulus of MgO under High Pressure

The pressure effects on melting temperature and shear modulus of MgO have been studied based on the semi-empirical approach in the Debye model. Numerical calculations have been performed up to 350 GPa. The present results contribute to the database of high-pressure melting. The melting points of MgO...

Zusammenfassung:The pressure effects on melting temperature and shear modulus of MgO have been studied based on the semi-empirical approach in the Debye model. Numerical calculations have been performed up to 350 GPa. The present results contribute to the database of high-pressure melting. The melting points of MgO at the core-mantle boundary (135 GPa) pressure and inner-core boundary (330 GPa) pressure are predicted, respectively, about 6,950 and 10,000 K.
