Abstract: | It is shown that a generalized version of inverted type equation of state (EOS) yields the recently proposed Saxena EOS J. Phys. Chem. Solids 65 (2004) 1561] for a particular value of the parameter related to , the pressure derivative of bulk modulus at extreme compression. It is found that some other inverted type EOS due to earlier workers can also be derived from a generalized version. A common feature of the inverted equations considered in the present paper is that they yield negative values for . This is in strong contradiction and violation of the theory of infinite pressure extrapolation due to Stacey. |
