ELECTRONIC TRANSPORT IN LIQUID LITHIUM-LEAD ALLOYS

Abstract
The self-consistent pseudopotential theory, developed previously for the binary alloys of simple metals, is applied to calculate the excess electronic charges on the electronegative ions, i.e. Pb ions, due to the partial localization of the valence electrons on these ions and the transport coefficients for the liquid Li-Pb alloy at different concentrations. It is found from this calculation that the partial localization of the valence electrons on the Pb ions in the Li-Pb alloy changes rapidly in going from the lowest concentration to the high concentration of Pb so that the transport coefficients of this alloy are strongly concentration dependent, as demonstrated in experiment. In addition, an improvement over the present type calculation is suggested.
