ZrO2-deficient compositions of NASICON (Na1+zZr2-x/3SixP3-xO12-2x/3 where 0 less than or equal to x less than or equal to 3) have been prepared in glassy form (sodium superionic conducting glass (NASIGLAS)) using the melt quench method. The corresponding glass-ceramics have also been produced by heat treatment at appropriate temperatures identified from DTA. From Si-29 MAS NMR, it is found that [SiO4] tetrahedra are predominantly Q(2) species for composition x = 3.0, but are mixed Q(2)-Q(1) for x < 3. Crystalline Na2ZrSi2O7 is found in all the corresponding glass-ceramic samples. The complex plane impedance method was used to determine the conductivity of NASIGLAS, which appears to be a complex function of mobility and concentration of Na+. Na-23 NMR indicates anomalous motion when x = 2.5. Low solubility of ZrO2 is noticeable in glasses with low value of x. (C) 2001 Elsevier Science B.V. All rights reserved.
