摘要

A semiempirical wide-range equation of state of granite and water based on decomposition of pressure and energy into a cold component and thermal nuclear and electronic components is presented. The thermal electronic components of energy and pressure are calculated with the Thomas–Fermi model which allows one to take into account both thermal and pressure ionization. The description of the cold isotherm is based on experimental data. Evaporation and dissociation are taken into account with corresponding addends in the free energy. Condensed state is described within the framework of the Debye approximation. The curves of coexistence of condensed and gas phases are calculated. Isoenergy curves in the density–temperature and density–pressure phases are considered.
