Abstract: This paper reports the kinetic process of Ag ion exchange for the polycrystalline Na-β"-Al2O3.The interdiffusion coefficients in the process of Ag+ and Na+ ion exchange have been calculated with an "one dimensional double side diffusion model". Microstructures of the samples were observed and analysed by XRD, EMPA, SEM. The results of the conductivity measurements for samples with Na+, Ag+ and Na+-Ag+ mobile ions are presented and explained
