摘要: 在水热晶化合成一系列NASICON型化合物的基础上,应用固体高分辨31P和29Si MAS NMR,研究了几种NASICON化合物的结构,观察其骨架原子P和Si在结构中的状态及分布,并解释了由于在结构中发生取代作用而引起,Si或P的化学位移的变化.

Abstract: The structure of several NASICON compounds prepared by hydrothermal crystallization were studied by solid -state high-resolution 31P and 29Si MAS NMR. The state and distribution of phosphorus and silicon in NASICON'S framework are understood, and the change in chemical shifts of 31P and 29Si caused by the substitution of lattice positions of atoms are explained. This is the first NMR investigation on the compounds of Na1-xZr2-xNbx(PO4)3 system.
