An essential and fundamental problem to determine a P-V-T thermal equation of state (EOS) of solid as a primary pressure standard is the fact that the pressure or volume dependence of thermal property of solid, that is necessary for the conversion of Hugoniot to isotherm, cannot be obtained experimentally. In this article, theory of P-V-T EOS of solid is reviewed first, and based on our recent ab initio results of gold, validity of previous P-V-T EOS models and especially volume dependence of Grüneisen parameter are discussed in detail.
