A theoretical study of the compression curves for NaCl

Abstract EN

The compression curves for NaCl have been calculated using Birch-Murnaghan, Vinet, Misra-Goyal, Bardeen, Brennan-Stacey and the modified Lennard-Jones equations of state.

The curves result from these equations of state has been compared with the results calculated from other theoretical methods based on Kumar equation.

The variation of V / Vo with T at different pressures are calculated using Kumar equation to show the effect of P and T at the same time on V / Vo.

The compression curves resulted from the used equations of state and Kumar equation at room temperature are plotted together with the experimental data of NaCl for the sake of comparison.
