We present a simple and straightforward relationship for evaluating the volume dependence of melting temperature based on the Lindemann's melting equation (F.A. Lindemann, Z. Phys. 11 (1910) 609) and the Al'tshular et al. model for the volume dependence of the Gruneisen parameter (L.V. Al'tshuler, S.E. Brusnikin, E.A. Kuz' menkov, J. Appl. Mech. Tech. Phys. 28 (1987) 129). The formula for the volume dependence of melting temperature obtained in the present study has been used to determine the results for aluminium up to a pressure range of 77 GPa. The results obtained for the melting temperature present a good agreement with the available experimental data.
