M_x^INa_(2-x)ZnSiO_4的离子交换法合成与表征

Characterization and Synthesis of M_x^INa_(2-x)ZnSiO_4 by Ion—Exchang Method

用中温水热合成的方法合成了MIxNa2-xZnSiO4离子导体.应用溶液电化学方法及固态电极方法研究了Na2ZnSiO4与K+和Ag+的离子交换性,对离子交换后得到样品的结构、密度及离子导电性进行了表征.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相符合.

Ionic conductor NaEZnSiO4 was synthesized by hydrothermal method NaEZnSiO4. k^＋ and Ag^＋ were investigated by solution electrochemical and solid state electrode methods the crystal structure density and ionic conductivity of ion- exchanged samples Na1. 1K0.9ZnSiO4 and Na1.2 Ag0.8ZnSiO4 were studied. Compared to other ion - exchange methods, higher 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.
