Recent Developments in Perovskite-Based Oxide-Ion Conductors
Recent advances in the study of oxygen-deficient perovskites and brownmillerite phases as oxygen ion conductors are reviewed. The structures of these phases containing oxygen vacancies are surveyed and the role of the oxygen vacancies with respect to the ionic conductivity in these materials is discussed in detail.
