Abstract

Isovalent substitution of Mn(II) for Mg(II) in the oxide ion conductor, La0.9Sr0.1Ga0.8Mg0.2O2.85, yields a new oxide ion conductor which exhibits an ionic conductivity (sigma = 4.6 x 10(-2) S cm(-1) at 800 degrees C) that is comparable to the conductivity of the Mg(II) analogue; interestingly, the Mn(Ir) oxide has a lower activation energy for conduction (E-a = 0.47 eV) than the Mg(II) oxide.
