SCHEDULED MAINTENANCE
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 (σ = 4.6 × 10–2 S cm–1 at 800 °C) that is comparable to the conductivity of the Mg(II) analogue; interestingly, the Mn(II) oxide has a lower activation energy for conduction (Ea = 0.47 eV) than the Mg(II) oxide.
