Abstract
The mixed alkali effect can simply be described by considering the change i n the mobility of ions when their concentrations change. The change of resi stivity through a maximum implies that the mobility of an alkali ion increa ses with an increase in its concentration. Relations ave given to follow th e change of mobility with composition. The parameters in these relations ca n be selected to get reasonable agreement between the determined and calcul ated resistivities.
