The problem for deriving an electron equationofstate in a given material by a selfconsistent field method is considered. Thermodynamic consistency of expressions for energy, entropy, and pressure in HartreeFock approximation is shown. A local exchange approximation (HartreeFockSlater approximation) is introduced on stepbystep basis, along with the expressions consistency for thermodynamic functions in this approximation. A relatively simple method for calculating thermodynamic electron functions in an arbitrary temperature and density material is proposed.
