This paper reports the research work on the preparation of La_ (1-x) Sr_xMnO_3 powder by complex method. The effects of drying process, thermal decomposition temperature and oxidation crystallization temperature on the properties of powders were discussed. Using x-ray diffraction, DTA was carried out on the powder drying, thermal decomposition process and phase analysis. The particle size distribution of the powder was measured. So as to select the best technology to prepare the air electrode material of a solid oxide electrolyte fuel cell.
