| Abstract: | Diffrent inverted
type equations of state (EOS) have been discussed, which express volume ratio
as a function of pressure for materials at a given temperature. It is shown in
the present study that some of these EOS do not satisfy the basic requirements
revealed from the fundamental thermodynamics for solids in the limit of extreme
compressions developed by Stacey. The critical test of EOS for solids under
extreme compressions by evaluating the pressure-volume derivative properties
viz. isothermal bulk modulus and its pressure derivative calculated for MgO and
NaCl up to extremely large pressures has been presented. Among the five equations
of state studied here, the inverted type of EOS due to Bose-Roy S and Bose-Roy P
has been found to be most satisfactory. A detailed comparison of this EOS has
been presented with the Keane’s EOS and the Stacey EOS. |
