Abstract
Negative deviations from Raoult's law in ternary liquid metal mixtures are modeled with the multicomponent ideal chemical theory (MICT) model. Expressions for the activity coefficients, partial molar enthalpies, and the stability function are derived and given as a function of the model parameters: Gibbs energy of compound formation, enthalpy of compound formation, and the heat capacity change of compound formation. Model predictions are given and compared with experimental measurements for three ternary magnesium systems. Experimental measurements of the magnesium activity coefficient at 1073 K in the Mg-Sb-BI and Mg-Pb-BI systems are presented and compared with MICT model predictions.
