✦ Synopsis

The stoichiometry, polymorphism and electrical behaviour of solid solutions Li,5_3xPr,,+,Ti0, with perovskite-type structure have been studied. Data are shown in the form of a phase diagram, XRD patterns for the three polymorphs, A, C, and p, temperature-and composition-dependence of their lattice parameters and Arrhenius conductivity plots. Microstructure and composition were studied by electron probe microanalysis. Maximum conductivity is 4 X 10e6 S cm-' at 25°C for x = 0.08. An insulating surface layer, seen in samples coated with Au electrodes, disappears in contact with molten LiClO,.
