Mixing properties of X–Pb, (X = Cd, In) liquid binary alloys

We study the mixing properties of Cd–Pb and In–Pb segregating alloy systems using the Quasi-chemical approximation model (QCAM) within the framework of Quasi-lattice theory (QLT). The energetics of mixing in liquid binary alloys has been analyzed through the study of the various thermodynamic quantities. Positive deviation from Raoultian behavior was observed in the mixing properties of the alloys calculated. Our results are in good agreement with reported experimental data and support a weak demixing tendency in both Cd–Pb and In–Pb liquid alloys.
