Resumen

The stoichiometry, polymorphism, and electrical behaviour of the solid solutions Pr_0.5+x-yBi_yLi_0.5-3xTiO₃ with perovskite-like structure have been studied. Data are given as a solid solution triangle, XRD patterns for two polymorphs T and O, the composition dependence of their parameters, and ionic conductivity plots. A region of perovskite-like solid solutions was obtained when the bismuth content in the general formula Pr_0.5+x-yBi_yLi_0.5-3xTiO₃ was y ≤ 0.10 and the lithium content was 0.033 ≤ x ≤ 0.133. The compounds are mixed conductors. With increasing amounts of lithium the ionic conductivity first increased, reached a maximum for x = 0.20, with a conductivity at 25 °C of 6.639·10^-3 S·cm^-1, and then decreased.
