Abstract
Abstract
We studied the melting temperatures of bismuth and antimony as a function of pressure in this paper because, unlike other solids, melting temperatures are found to fall with increasing pressure. A phenomenological model is proposed to represent the melting temperature as a function of pressure in both solids using Lindemann’s criterion. The computed results are found to be very close to the experimental data. The average absolute percentage relative deviation (AARD%) in bismuth is 0.012, 0.038 in antimony (set-1) and 0.128 in antimony (set-2). Furthermore, the minimum condition is obtained, which gives the pressure at the minimum melting temperature.
