Высокотемпературный ионный и электронный транпорт в перовскитоподобных оксидах SrFe1-xSixO3-δ

Abstract

Conductivity and oxygen content in SrFe1-xSixO3-δ were measured in a wide range of partial oxygen pressure at temperatures 800-950°C. The results obtained allowed one to evaluate partial contributions o f oxygen ions and electron carriers of p - and n - types to charge transfer. Concentration and mobility o f charge carriers were calculated. The effect of partial substitution of iron by silicon on transport properties is discussed.
