Abstract: K-primed equations of state for solids are more advantageous than the conventional pressure-volume relationships for studying higher derivatives of bulk modulus and thermoelastic properties. The reciprocal K-primed quadratic equation is consistent with the first-principles results determined from the augmented plane wave method for metals, non-metals and diatomic solids, has been studied in the present paper. The values of pressure, bulk modulus and its pressure derivative based on the first-principles in case of different solids are found to satisfy the reciprocal K-primed quadratic equation.
