Effect of B-site substitution on the stability of La0.2Sr0.8Fe0.8B0.2O3-delta, B = Al, Ga, Cr, Ti, Ta, Nb
Lohne, Ørjan Fossmark; Gurauskis, Jonas; Phung, Tan Nhut; Einarsrud, Mari-Ann; Grande, Tor; Bouwmeester, Henny J. M.; Wiik, Kjell (Journal article; Peer reviewed, 2012)Single phase, cubic perovskites of composition La0.2Sr0.8Fe0.8B0.2O3 − δ, B = Al, Ga, Cr, Ti, Ta and Nb, were prepared by spray pyrolysis from aqueous precursor solutions. The effect of B-site substitution on the stability ... -
Oxygen Non-Stoichiometry and Electrical Conductivity of La0.2Sr0.8Fe0.8B0.2O3 − δ, B = Fe, Ti, Ta
Lohne, Ørjan Fossmark; Phung, Tan Nhut; Grande, Tor; Bouwmeester, Henny J. M.; Hendriksen, Peter Vang; Søgaard, Martin; Wiik, Kjell (Journal article; Peer reviewed, 2014)The oxygen non-stoichiometry was determined by coulometric titration for the perovskite oxides La0.2Sr0.8FeO3 − δ and La0.2Sr0.8Fe0.8B0.2O3 − δ (B = Ti4 + and Ta5 +) in the temperature range 600 °C ⩽ T ⩽ 900 °C and the ... -
Structure, electrical conductivity and oxygen transport properties of perovskite-type oxides CaMn1−x−yTixFeyO3−δ
Ruhl, Rian; Song, Jia; Thoréton, Vincent; Singh, Sathya Prakash; Wiik, Kjell; Larring, Yngve; Bouwmeester, Henny J. M. (Journal article; Peer reviewed, 2019)Calcium manganite-based perovskite-type oxides hold promise for application in chemical looping combustion processes and oxygen transport membranes. In this study, we have investigated the structure, electrical conductivity ...
