| Abstract: | Perovskite oxides SmMnO3 have been prepared by citric acid complexing, carbonate coprecipitation, nitrate direct decomposition and ceramic method. The effects of preparation methods and the calcination temperature on the formation of perovskite structure were studied by XRD and TPR technique, and the key steps in formation of SmMnO3 are discussed.
