Characteristics of lanthanum strontium chromite prepared by glycine nitrate process

La1-xSrxCrO3 (x = 0, 0.1 0.15, 0.2 and 0.3) (LSC) powder materials were syn thesized by the glycine-nitrate-process. XRD analysis indicated that the po wder exhibits a single phase with perovskite structure. The mean primary pa rticle size of the powder was around 30 nm based on the morphology observat ion by TEM. The sinterability of the powder was improved as Sr doping conte nt x increases in the investigated doping range. The electrical conductivit y measurement of the sintered material revealed that LSC reached a maximum at x = 0.2. The synthesized La0.8Sr0.2CrO3 powder was used to make a coatin g layer on the substrate of Cr plate by plasma flame spraying technique. Th e preliminary experimental results showed that LSC coated Cr could be used as the interconnect for SOFC. (C) 2000 Elsevier Science B.V. All rights res erved.
