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.
