Abstract

Superfine powders of La 2/3-x Li 3x TiO 3(x=0.11, LLT) perovskite-type oxides were synthesized by a citrate method. The factors influencing on the formation of sol and gel as well as the crystal structure and morphology
of synthesized powders were examined. The effects of sintering temperature on the conductivities of the ceramics were investigated. The results show that the highest electrical conductivity can be obtained for the sample sintered at 1200℃, which is approximately 150℃ lower than that of samples synthesized by the conventional solid state reaction method. The grain and total lithium ion conductivities of the LLT ceramics sintered at 1200℃ are 9×10-4 S/cm and 2.15×10-5 S/cm at room temperature, respectively.

Key words： La2/3-xLi3xTiO3; citrate sol-gel process; lithium ion conductor; electrolyte
