AbstractThe lithium ionic conducting perovskite La0.57Li0.3TiO3 has been synthesised via a sol-gel method at a temperature of 700 °C. The crystallinity of the product can be greatly increased by further heat treatment at 1000 °C. In this paper the product of the sol-gel synthesis is compared with the product of conventional solid-state synthesis, and the influence of the synthesis method as well as of quenching on the crystal structure and ionic conductivity has been studied. AC-impedance measurements show two contributions to the ionic conductivity, which can be adscribed to intergranular and intragranular effects, respectively. A lower intergranular resistivity is observed for sol-gel samples, while quenching mainly affects the materials prepared by solid-state reaction. The crystal structure of the material prepared by the sol-gel method is identical to that of the material prepared by the solid state reaction, although the synthesis temperature is nearly 600 °C lower. A tetragonal superstructure is observed when either type of material is slowly cooled from 1300 °C. Quenching from the same temperature results in the suppression of that superstructure.
