A new equation of state based on Grover, Getting and Kennedy's empirical relation between volume and bulk modulus. The high-pressure thermodynamics of MgO

Abstract

The empirical linear relation between volume and logarithm of bulk modulus, discovered by Grover, Getting and Kennedy, is taken as the basis for a new pressure–volume equation of state. This linear relation and the equation of state have the same two substance-dependent parameters, the values of which can be derived from low-pressure data. For MgO, in the temperature range 100–3100 K and the pressure range 0–225 GPa, it is shown that the new methodology allows the careful calculation of high-pressure thermodynamic properties: all available experimental data are reproduced with great precision.
