Abstract

Doppler broadened lineshape and ionic conductivity measurements have been made in the NASICON analogue Na2 (La, Al) Zr (PO4)3 synthesized with four different concentrations of ZrO2 (2, 2.2, 2.8 and 5.2 by wt.%) in the nutrient at room temperature. The lineshape parameter S is calculated for each concentration and it shows maximum value and the a.c. ionic conductivity σ shows minimum value for the material with 2.8 (wt.%) concentration of ZrO2 in the nutrient. An attempt has been made in correlating the changes in S parameter with σ. The results show that the defect density is maximum for the material with 2.8 (wt.%) concentration of ZrO2 for which the conduction paths of Na+ ion are restricted.
