A study was made of the field-assisted diffusion of Ag ions from Ag films and into soda-lime glass. This indicated that it was necessary to take account of the concentration-dependence of the self-diffusion coefficients of both the Ag ions and the Na ions, in a pseudo mixed-alkali effect, in order to predict the Ag diffusion profiles accurately. A field-assisted diffusion model that incorporated this effect was developed, and model coefficients were deduced. The model was applied to post-bake diffusion and deep field-assisted diffusion profiles.
