An empirically modified Nernst‐Einstein‐type equation is proposed to relate the electrical conductivity of mixed‐alkali glasses to the self‐diffusivities of the alkali ions. Conductivities were calculated for 3 glass systems using measured self‐diffusivities and the proposed equation. These calculated conductivities and those measured directly agree quite well.
