Abstract
We treat ionic diffusion in liquid (Li,K)Cl mixtures by an approach originally due to Zwanzig, which evaluates the Green-Kubo time correlation formula by a jump-diffusion model involving an average vibrational frequency and an average residence time for each ionic species. These model parameters are calculated from the pair structure of the melt and from pair potentials. The diffusion coefficients of K{sup +} ions is found to overtake that of Li{sup +} ions with increasing content of KCl, in agreement with the experimental reversal of the electrical mobilities of the two cations discovered by Chemla. (author). 20 refs, 2 tabs.
