摘要：
The paper presents a simple technique for synthesis of La1-xSrxCoO3 (v=0-0.3) nanopowders by calcining maleate-based precursors. The complex precursors were characterised by chemical analysis, electronic and FT-IR spectra and DTA-TG analysis. The XRD data for La1-xSrxCoO3 show that the samples are single phase with rhombohedral distorted perovskite structure. Specific surface area results of La1-xSrxCoO3 samples indicated values in the range 30-38 m(2)/g, which are high values for perovskite-type oxides. (C) 2004 Elsevier B.V. All rights reserved.
