Crystalline perovskite La0,67−xLi3xTiO3 with x = , and were prepared by solid-state-solution reactions at 1350◦C from TiO2, La2O3 and Li2CO3. Crystalline structure of these compounds was analyzed by XRD method. The ionic conducting property of −xLi3xTiO3 was characterized on system with impedance technique using fitting software program available in the equipment. The highest ion conductivity at room temperature was found for the compound with x = , namely σ = × 10−5Scm−1. With increase of temperature the ionic conductivity increased and at 200◦C it reached a value in two orders in magnitude higher (6×10−3Scm−1). The activation energy of the compounds was determined on Ln(σ)vs. 1/T plots and found to be as low as eV. | Crystalline perovskite xLi3xTiO3 Preparation and ionic conducting characterization
