【Abstract】 La 0 7 Sr 0 3 MnO 3 used as cathode materials for SCFE was synthesized through the sol gel process. Ethylene glycol and citric acid were used to make dissolvent and peptization. The particle diameter distribution of powders is 40 to 80nm. The averaage particle size of powders is 70nm. The cathode material La 0 7 Sr 0 3 MnO 3 of perovskite type was synthesized at 1000℃. The electronic conductivity of La 0 7 Sr 0 3 MnO 3 is higher than 10 4s·m -1 at 1000℃.更多还原
