Abstract: Ion-exchange properties of Na5YSi4O12 with K+ and Ag+ were investigated by solution electrochemical and solid state electrode methods, The crystal structure, density and ionic conductivity of ion-exchanged samples KNYSand AgNYSwere studied.Compared to other ion-exchange methods,mgher ion-exchange degree can be obtained by the two methods mentioned above,and the result of elementary analysis coincides well with that of density measurement.
