Ion-exchange and the electrodiffusive penetration of lithium ions into the surface layer of glass

Abstract: The values given in Table 1 for the diffusion coefficients are, regarding orders of magnitude, in good agreement with those obtained by other research workers [2] for glasses of a similar composition. The values of the activation energy of diffusion calculated from the temperature dependence of the diffusion coefficients for the same concentration of lithium ions are 30-33 kcal/mole and this also is in good agreement with the data of the same authors.
