The equation of state for NaCl crystal is investigated using the recently revised generalized Huggins‐Mayer potentials. The calculations are performed for pressures up to about 200 × 10 8 Pa and at different temperatures ranging from 298 to 773 K. The calculated values are found to agree with the experimental data. An investigation of the pressure dependence of the Grüneisen parameter is also presented using different existing theories. A comparison of the calculated and experimental values reveals the superiority of one theory over the other.
