Studies on Hydrothermal Synthesis,Structure and Properties of NaSn_2(PO_4)_3

应用水热合成技术制备了具有NASICON型结构的NaSn_2(PO_4)_3离子导体.研究了其结构与电导性能.结果表明,水热合成制备NaSn_2(PO_4)_3离子导体化合物,是一条新的途径,它比传统的高温固相反应方法更加方便有效,尤其容易获得较纯的物相及单晶,并且水热晶化产物与固相反应产物具有相同的结构和性能.

NaSn_2(PO_4)_3 with NASICON structure was prepared by using hydrothermal techniques.The structure and conductivity of the samples were studied.The results show that the hydrothermal synthesis is a new route for preparing NaSn2(PO4)3 compound.This method is more convenient and effective than the conventional solid-state reaction method at high temperature and the pure phase and single crystal can be obtained easily.The structure and properties of the product obtained by hydrothermal crystallization are similar to those of the sample yieled by solid-state reaction.
