摘要：

Ultrafine lithium ion conducting La2/3-xLi3xTiO3 (x = 0. 11, LLT) powder was synthesized by a simple polymerizable complex method based on the Pechini-type process. The formation mechanism, homogeneity and microstructure of the samples were investigated by thermal analysis (TG/ DTA), X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). XRD analysis indicated the formation of pure perovskite-type phase. The powder synthesized at a temperature as low as 900 degrees C in a much shorter time than solid-state reaction method was well crystallized. The lithium ion conductivity of the LLT ceramics sintered at 1200 degrees C was found to be 9 x10(-4) S/cm at room temperature. (c) 2006 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
