Abstract

Ceramics powder of Li7La3Zr2O12 (LLZ) was prepared by a sol-gel method from the stoichiometric mixtures of nitrate salt as precursor. The LLZ resin was heated at temperature of 325ï‚°C for 2 hours and at various calcination temperatures between 600-900 ï‚°C for 10 hours. The powders obtained were characterized by Thermal Gravimetry Analysis (TGA) and Fourier Transform Infrared (FTIR) to verify the thermal decomposition of the powders and the presence of carbonate group in the compound. TGA results indicate that all the samples were almost completely decomposed at ~800 ï‚°C except for sample with CTAB surfactant that showed the lowest thermal decomposition temperature at 733 ï‚°C. FTIR analysis showed that the intensity of carbonate group were decreased due to the increasing of temperature. It was found that the different surfactants used lead to the different characteristics of the LLZ powder.

Key Words   
LLZ ceramics powder, modified sol-gel method, surfactants, thermal decomposition
