Аннотация:The structure, microstructure and conductivity parameters of lithium-lanthanum titanates (La1/2Li1/3+x)TiO3(x = 0; 1/10; 1/6; 1/5; 1/4) have been studied. Ionic conductivity has been found to decrease when lithium content increased due to both the cell volume and the A-site vacancy content decreasing. The anomalies on temperature dependences of dielectric permttivity and dielectric losses near 500 and 850K have been observed which may be connected with structural transformation and cation disordering in A-sublattice.
