Abstract
The chemical transformations involved in the synthesis of the NASICON-type compound LiZr2(PO4)3 were studied by thermogravimetry and x-ray diffraction. The results demonstrate that, during heat treatment of a 3Zr(HPO4)2 · 2H2O + Li2CO3 + ZrO2 mixture, the formation of the NASICON phase begins at 600°C. Further heating, however, leads to the concurrent formation of zirconium diphosphate and uncontrolled lithium losses because of the high volatility of Li compounds. A well-crystallized, high-conductivity NASICON phase is formed only above 1100°C. Phase-pure LiZr2(PO4)3 can only obtained by a two-step procedure.
