Abstract

The Nie expression is amended in such a way that the expression follows the infinite pressure behaviour, i.e., P → ∞ or V → 0. A new empirical relationship is developed to predict the values of volume dependence of Grüneisen parameter. NaCl and ε-Fe have been employed to test the suitability of the expression. The results obtained reveal that the relationship is reliable as there is a good agreement between the calculated and the experimental data.
