Abstract

Perovskite-type oxides are mixed electronic and ionic conductors. The properties of these oxides are associated with their high oxygen ionic diffusivity, high oxygen nonstoichiometry and high electrical conductivity. The studies reveal that perovskite oxides are defect compounds and the substitution of Sr for La can modify their electronic structures. The results indicate that some of cobalt in the oxides change from low valence state to high valence state and high density of oxygen vacancies are formed as a result of the substitution of Sr for La.
