摘要：
A very simple, cost-effective, chloride- and alkali-free, carbonate co-precipitation synthesis in aqueous medium was applied in the preparation of perovskite-type lanthanum manganese oxide-based powders, i.e. La0.70Sr0.30MnO3-delta (LSM) and La0.75Sr0.25Cr0.5Mn0.5O3-delta (LSCrM). The precursors so obtained yielded nano-structured perovskite oxides when treated at 900A degrees C and 800A degrees C, respectively. The measured BET surface areas were in the low-end range for high temperature oxides (4 m(2) g(-1) and 10 m(2) g(-1)) but the X-ray crystallite size was as low as 50 nm for LSCrM and 90 nm for LSM.
