Energetics of Cd-based binary liquid alloys

Abstract The thermodynamic properties such as, free energy of mixing ( G M ), heat of mixing ( H M ), entropy of mixing ( S M ) and microscopic properties such as, concentration fluctuation in long wavelength limit ( S CC (0)), Warren–Cowely short range ordering parameter (α 1 ), ratio of mutual and intrinsic diffusion coefficients ( D M / D id ) of two Cd-based liquid alloys have been studied by using two different models. The properties of Cd–Hg liquid alloy at 600 K have been studied on the basis of regular solution model, and the properties of Cd–Na liquid alloy at 673 K have been studied on the basis of quasi-chemical expression for weakly interacting system.
