Energetics of Compound Formation in Binary Sb-Sn Liquid Alloys

Abstract

Energetic of mixing and symmetry at equiatomic composition in liquid Sb-Sn alloys has been investigated using complex formation model. Assuming the order energy parameters w, l12, l13, l23 are temperature dependent, information on Gibbs free energy of mixing at temperature of 905 K and other thermodynamic properties of liquid Sb-Sn alloys was discussed. Gibbs free energy of mixing was modelled using the assumed order energy parameters. Negative deviations from Raoult’s law observed and reported. Our detail examination of the Sb-Sn system suggests that the liquid alloy exhibits compound formation over the whole concentration range, and symmetry in equiatomic composition was observed, though the tendency of the compound formation in the alloy has been found to be weak.  &nbsp
