A thermodynamic study has been carried out on the Bi-Sn-Sb ternary alloy system. The Gibbs energy of individual phases has been approximated using the regular solution, two-sublattice model, and the thermodynamic parameters for each phase have been evaluated using the available experimental information on phase boundaries and other related thermodynamic properties. Thermal analysis experiments have also been performed on several ternary alloys to re-examine and augment the available ternary experimental data. The set of evaluated thermodynamic parameters arrived at in this study, enables reproducible calculations of the liquidus and solidus temperatures and vertical section diagrams quite satisfactorily.
