NONIDEAL BEHAVIOR IN LIQUID METAL SOLUTIONS. PART 1 - PHYSICAL THEORY MODEL.

A 'physical' model of liquid metal solutions, based on the concept of electron transfer, has been used to calculate mixture properties for systems with positive or small negative deviations from Raoult's law. It gives very good quantitative results for excess Gibbs energies and excess enthalpies, and qualitatively correct results for excess volumes. It has been used successfully to predict solid-liquid and liquid-liquid equilibria, and the extension to multicomponent systems is discussed. The physical significance of the charge transfer parameter is described.
