Abstract: | In the present communication we have reviewed some inverted type equations of state for solids under high pressures. An inverted
equation of state (EOS) gives volume as a function of pressure for a solid under isothermal conditions. We have considered
various equations of state proposed by earlier workers which express volume as a function of pressure. Expressions for bulk
modulus and its pressure derivatives based on such EOSs are obtained and reported here. It is emphasized here that the high
pressure derivative properties are very sensitive to the forms of equations of state representing volume-pressure relationships.
We have also studied the thermoelastic properties of solids based on pressure derivatives of bulk modulus. Applications have
been extended in the present review article to the solids which are metals as well as non-metals including geophysical minerals
present in the lower mantle and core of the Earth. |
