A realistic equation of state for solids. The high pressure and high temperature thermodynamic properties of MGO
Source abstract
Abstract
As has been found for pure metals, there exists a linear relationship between molar volume and the logarithm of bulk modulus. This relation is also valid for oxide and silicate substances. From the relationship, an equation of state has been developed and applied to the substance MgO. With this equation of state and by using experimental thermodynamic data at 1 bar pressure only, it is possible to make accurate predictions of thermodynamic properties at very high pressures and temperatures. Thermodynamic anomalies encountered in using e.g. a Birch-Murnaghan equation of state do not occur and the number of adjustable parameters is reduced.
