“…Singh et al [4] have successfully used it to study the thermodynamic properties of Li-Mg liquid alloys. This has encouraged us to apply it to the Li-Cd system, which is a suitable candidate for the regular solution model of the quasi-chemical theory because the size effect is negligible and the free energy of mixing is almost symmetrical about the mole fraction Ccd = Li-Cd exhibits interesting concentration dependent physical properties [5,6], and there is strong indica tion for deviations from ideal mixture behaviour.…”

The quasi-chemical model based on pairwise interactions is used to study the concentration dependent thermodynamic properties of Li-Cd liquid alloys. Special attention is given to the concentration-concentration correlation function in the long wavelength limit [Scc(O)] and the chemical short-range order parameter (CSRO). The activity, free energy of mixing, Scc(O) and CSRO are computed as functions of temperature and concentration.

The thermodynamic properties of Sb-Sn and In-Sn liquid alloys have been studied using the quasi-chemical model for compound forming binary alloys and that for simple regular alloys. The concentration fluctuation S cc (0) and the Warren-Cowley short-range order parameter (α 1 ) were determined for the whole concentration range at a temperature of 770 K. The surface tensions of these liquid alloys were determined for the whole concentration range by using energetics determined from thermodynamic calculations. In all calculations, In-Sn manifested properties very close to alloys of ideal mixing, while Sb-Sn showed properties that are asymmetric about equiatomic composition. Our results suggest that a weak complex of the form SbSn2 could be present in the Sb-Sn alloy at a temperature of about 770 K.
