Abstract:

The electric conductivity of perovskite-like Ba-2(In1 - x Al (x) )(2)O-5 solid solutions (0 < x a parts per thousand currency sign 0.20) characterized by structural disordering in the oxygen sublattice was studied as a function of temperature and partial pressure of oxygen in an atmosphere with a low content of water vapors ( = 3 x 10(-5) atm). When In3+ was partially replaced by Al3+, the oxygen ion conductivity increased because of the disordering of oxygen structural vacancies, leading to a significant increase in the total electric conductivity of the samples.
