Abstract

The stoichiometry, stability and polymorphism of the perovskite-related solid solutions, Li0.5−3xRE0.5+x TiO3: RE = La, Nd, has been studied. For both series, the data are presented in the form of a temperature vs. composition phase diagram. Unit cell data for the different polymorphs (three in the La system, four in the Nd system) are presented, together with data on the composition and thermal history dependence of the lattice parameters. The phase composition and microstructure of selected ceramic samples were analysed by electron microprobe techniques.
