“…Table 6 presents the estimated Sn activities in Sn-Sb-Bi liquid ternary alloys at 900 K using Eq. ( 10), and the results are contrasted with the reference's experimental data (Katayama et al, 2005). With the exception of a few variations, the agreement between our computed activities and the experimentally measured values is satisfactory across all three sections of Sb:Bi = 1:3, 1:1, and 3:1.…”

“…The model of a quasi-lattice was employed to investigate the thermodynamic characteristics of liquid alloys composed of Sb-Sn and In-Sn (Anusionwu, 2006). The activities of tin in liquid Sn-Bi, Sn-Sn, and Sn-Sb-Bi alloys were determined by measuring the electromotive force (emf) in a galvanic cell with a fused salt electrolyte in the temperature range of 700 to 1000 K for the entire composition range by Katayama et al (Katayama et al, 2005). This was an experimental method, and there was a lack of study of the thermodynamic properties of the Bi-Sb sub-binary system in the study of Katayama et al The activity of all components in Bi-Sb-Sn was predicted by Awe et al in 2014 in three cross-sections taken from the corner of each metal, with the molar ratios of the other two components being 1:3, 1:1, and 3:1 in the temperature range of 500-1000 K (Awe & Oshakuade, 2014).…”

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.
