摘要：
A series of Fe 2-x Cr x O 3 ( x=0, 0.4, 0.8, 1.2, 1.6, 2.0) mixed oxides have been prepared with the chemical coprecipitation method and characterized by specific surface area, transmission electron microscopy (TEM), powder X ray diffraction (XRD), IR and Mssbauer spectroscopy. Single phase Fe Cr mixed oxide nano crystalline powders with corundum structure are obtained, and the results of the five characterization methods are well accordant with each other. Furthermore, gas sensitive properties of the sensors made of the oxide powders have been studied.
