Melting temperature of copper and silver up to high pressure are studied based on Lindemann’s melting criterion, where the mean square deviation of the thermal vibrations of the lattice and spacing parameters calculated by the statistical moment method (SMM). We obtain the melting temperatures of these metals are simple explicit functions of pressure, without adjustment parameters. Numerical results of the melting temperatures of copper and silver up to 1500kbar are in excellent agreement with the experimental data and are compared with results calculated by other theories.
