Paper Abstract

With the thermal diffusion method, the Tl+ -ion diffusion process in Tl+-Na+ ion-exchanged glass is in details described by the electroneutrality field and the stress, which are generated by the huge dimension difference for Tl+ and Na+ ions and the large difference in diffusion coefficients between Tl+ and Na+ ions. The results of the theoretical analysis and the experiment data by X-ray energy dispersive spectra indicate that the Tl+ diffusion process is found to be a new diffusion law.
