Abstract:

Various forms of the equation of state for studying high-pressure behavior of solids have been developed by numerous investigators using phenomenological approaches. A common feature of the phenomenological equation is that they present the relationship between pressure and volume which can be expressed analytically involving two quantities only, viz Bo, B0’ respectively, the isothermal bulk modulus and its first pressure derivative, both at zero pressure. The present proposal which intend to compare the efficiency of the four equations under close examination reports the V/Vo versus P derived from the new modified forms of Murnaghan equations Birch equation (BE) and Freund-Ingalls (FIE) equation obtained for the best agreement with the available experimental data.
