Electrical properties of (La 1/2Li 1/3 + x)TiO 3 solid solutions

Data are presented on the phase composition, structure, and electrical properties of (La 1/2Li 1/3 + x])TiO 3 solid solutions with x = 0, 1/10, 1/6, 1/5, and 1/4. The introduction of superstoichiometric lithium oxide into the starting mixture is shown to reduce the ionic conductivity of the solid solutions, which is interpreted in terms of cation ordering and lattice contraction. © Pleiades Publishing, Inc., 2006
