title: Ionic conduction of lithium for (Li0.25La0.25)(1-x)Ca(0.5-x)TaO3 ceramics.
abstract: The ion transport properties of perovskite-type compounds (Li0.25La0.25)(1-x)Ca(0.5x)TaO3, as lithium ionic conductors, are investigated (0 ≤ x ≤ 0.5). The compounds were synthesized by using a solid state reaction. X-ray diffraction (Li0.25La0.25)(1-x)Ca(0.5x)TaO3 indicates a structure that is transformed from cubic to tetragonal. The ion conductivity of lithium at room temperature decreases with an addition Ca2+ as a result of the decrease in lattice parameters resulting from the Ca2+ concentration.
