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.

Key words: Hydrotbennal synthesis, Ionic conductor, NMR
