Entropy of mixing for AgxIn1−x and AgxSn1−x liquid binary alloys

The entropy of mixing for AgxIn1−x and AgxSn1−x liquid binary alloys has been systematically investigated by using the perturbation theory. The interionic interactions as one of the basic ingredients are described by a local model pseudopotential. Since the metals forming the concerned alloys are less simple in nature the effect of the sp-d hybridization is appropriately taken into account through the interionic interactions. Results of our calculations across the full range of Ag concentrations are found to be good in agreement with the available experimental data.
