Activity Coefficients of Lithium Dilute in Binary Alloys: Measurements and Calculations (Al-Sn; Tl-Bi; Bi-Pb)

摘要

Electromotive force measurements of the activity of lithium dilute in three binary solvents (Al-Sn, Tl-Bi, and Bi-Pb) have been carried out at constant temperature. The variations of the activity coefficients of Li as a function of the composition of the solvent are analyzed in terms of three different models, the quasi-chemical theory, the Wagner model, and the coordination cluster theory. This last model appears to provide an excellent interpretation of the experimental results. 4 figures. (ERA citation 08:032177)
