Methods of X-ray diffraction analysis, impedance spectroscopy, and scanning electron microscopy were used to examine how thermal treatment modes affect the transport properties and microstructure of a lithium-conducting oxide ceramic of composition Li0.33La0.56TiO3, produced from powders synthesized by the sol-gel method. It was found that the cubic structure of Li0.33La0.56TiO3 can be stabilized as a result of quenching after the high-temperature of sintering at 1150°C. The conditions were determined in which Li0.33La0.56TiO3 ceramic samples can be obtained with bulk ion conductivity of ∼1 × 10−3 S cm−1 at 20°C, which corresponds to the maximum values for the ceramic based on lithium-lanthanum titanate.
