摘要
Electrical properties of perovskite Y0.08Sr0.92Ti0.92Nb0.08O3-delta after reduction in different conditions were studied. Relatively high electrical conductivity in samples reduced in ammonia was observed. The conductivity of Y0.08Sr0.92Ti0.92Nb0.08O3-delta reduced in ammonia at 1500 degrees C was of about 600S/cm at 200 degrees C. Conductivity after reduction in ammonia at 1500 degrees C was stable both in hydrogen and oxygen atmosphere up to 600 degrees C. Reduction Y0.08Sr0.92Ti0.92Nb0.08O3-delta in ammonia causes nitrogen incorporation into perovskite structure of Y0.08Sr0.92Ti0.92Nb0.08O3-delta. (c) 2008 Elsevier B.V. All rights reserved.
