“…However, the toxicity of lead and its harmful environmental effects have led to strict regulations, such as the European Union's RoHS (Restriction of Hazardous Substances) directive, which restricts the use of lead in electronic and electrical equipment. (Abtew & Selvaduray, 2000;Hindler et al, 2010;Knott & Mikula, 2002;Liang et al, 2021;Moelans et al, 2003). Therefore, in the present era, the utilization of lead has been prohibited globally (Suganuma, 2001).…”

The concentration-dependent properties, like the constituents’ activities for the binary liquid alloys like Sb-Sn at 905 K, Bi-Sn at 600 K, and Bi-Sb at 1200 K, and the integral Gibbs free energy of mixing, ΔGXS, of the correspondent alloys were computed using the molecular interaction volume model (MIVM). Further, the model has been used to compute the activities of the component Sn in the ternary Sn-Sb-Bi system at 900K at the three cross-sections, i.e., Sb:Bi = 1:3, 1:1, and 3:1. The theoretical data have been analyzed with the corresponding experimental data accessible in the literature. An acceptable concurrence has been obtained, with some inconsistencies. The activities of the ternary alloys along the three cross-sections, i.e., Sb:Bi = 1:3, 1:1, and 3:1, show that the deviations change from positive to negative with increasing Sb content. The results confirm that MIVM is a good model for estimating the thermodynamic properties of binary and ternary systems.
