摘要：

Solid-state electrolyte (SSE) with tetragonal structure Li7La3Zr2O12 (LLZO) is prepared by solid state reaction. Investigation of heat treatment temperature and time are observed. Increasing temperature from 700 degrees C to 950 degrees C improves structure purity and stability. Synthesis at 700 degrees C show appearance of La2Zr2O7 phase, however 750 degrees C synthesis sample material is free of that impurity. Heat treatment time exhibits the biggest sintering time provide small amount of Li2CO3 impurity. Crucible material influences by formation of Li2ZrO3 and Li2CO3 impurities at 900 degrees C and 6 h synthesis. (C) 2019 Elsevier Ltd. All rights reserved.
