The synthesis process for La1-xSrxMn1-yCoyO3-delta (x = 0.2, 0.3; y = 0.2, 0.8, designated as LSMC below) perovskite oxides prepared by solid state reaction was investigated using DSC/TG, XRD, EPMA and particle size analysis methods. It was found that LSMCs were all of single phase and the synthesis process might be divided into three stages: the decomposition of reactants, the formation of LaMn(Co)O-3-based oxides, and the formation of LSMC solid solution. Typical average and the peak value of particle size, and the specific surface area are 14.65 mum, 16.4 mum and 1.38 m(2)/mL, respectively, for mixed reactants and are 23.81 mum, 32.11 mum and 0.5 m(2)/mL, respectively, for powder synthesized at 1200 degreesC for 8 h in air.
