摘要：

An equation of state for MgO is calculated for conditions of high pressure and temperature using atomistic simulations within the quasiharmonic approximation with two-body potentials and a simple shell model. It is shown that experimental Hugoniot data can be reproduced accurately; other important properties are also examined including various quantities of geophysical interest. Results for the Helmholtz free energy and internal energy surfaces A(V,T) and U(V,T) are presented in parametrized form.
