Synthesis and Thermal Characterization of NZP Compounds Na1-Xlixzr2(Po4)3(X= 0.00-0.75)

Abstract

NZP composition Na1-xLix(PO4)3, x=0.00-0.75 has been synthesized by the method of solid state reaction from Na2CO3.H2O, Li2CO3, ZrO2 and NH4H2PO4, sintering at 1050-1250oC for 8hours only in other to determine the effect on thermal and other 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 1000oC. It was observed that the increase in lithium content of the samples increases 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 is observed to be above 640oC.The sample with the highest lithium content, x= 0.75 exhibited the greatest thermal stability over the temperature range.
