摘要： 用溶液电化学方法及固态电极方法研究了Na5YSi4O12(NYS)与K+和Ag+的离子交换性质,对离子交换后得到的KNYS和AgNYS样品的结构、密度及离子导电性质进行了表征。与其它离子交换方法相比,上述方法可获得较高的离子交换度,而且元素分析结果与密度测试结果符合良好。

关键词: 离子交换, NYS, 离子电导率, 活化能

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.

Key words: Ion-exchange, NYS, Ionic conductivity, Activation energy
