摘要：

The improved Tosi-Fumi pair potential has been employed to simulate the melting behavior and Gruneisen parameters of sodium chloride (NaCl) using molecular dynamics (MD) method at constant volume. The melting curve of NaCl is compared with the experimental data and other calculations in a pressure range from 0 to 144 GPa. The simulated results validate the amount of 20% superheating of the NaCl solid and yield an approximate power law dependence of the Gruneisen parameter (gamma) on compression gamma = gamma(0)(V/V-0)(q), with q approximate to 1.078, in the temperature range from 298 to 1073 K and pressure range from 0 to 60 GPa.
