Energies of Activation for Self-diffusion of Alkali Metal Ions in Analcite

Article metrics

Abstract

THE self-diffusion coefficients and energies of activation for migration of alkali metal cations in analcite have recently been measured1. We now find that when these energies are plotted against α1, the polarizabilities of the cations, the linear graph shown in Fig. 1 is obtained. This line can be represented by the equation: where E is expressed in kcal./gm. ion and α1 in cm.3/ion.
