Abstract

Sodium zirconium phosphate (NZP) composition Na1−x Li x Zr2(PO4)3, x = 0.00–0.75 has been synthesized by method of solid state reaction method from Na2CO3·H2O, Li2CO3, ZrO2, and NH4H2PO4, sintering at 1050–1250 °C for 8 h only in other to determine the effect on thermal properties, such as the phase formation of the compound. The materials have been characterized by TGA and DTA thermal analysis methods from room temperature to 1000 °C. It was observed that the increase in lithium content of the samples increased thermal stability of the samples and the DTA peaks shifted towards higher temperatures with increase in lithium content. The thermal stability regions for all the sample was observed to be from 640 °C. The sample with the highest lithium content, x = 0.75, exhibited the greatest thermal stability over the temperature range.
