Abstract
It is known that the Haven ratios, H R, in mixed alkali glasses increase anomalously. The authors have attempted to explain quantitatively such anomalous behavior by introducing the thermodynamic activity term in the Nernst-Planck equation, which results from the attractive interaction between dissimilar alkali ions via oxygen ion. As a result, it was found that the apparently large values of H R in the mixed alkali glasses can be reduced to the same as in the single alkali glasses when corrected by the thermodynamic term. This fact also indicates that the ionic diffusion mechanism in mixed alkali glasses does not differ from that in single alkali glasses.
