摘　　要：在αFe_2O_3中依次累积加入K_2O、Cr_2O_3、CuO、MGO和SiO_2形成不同混合物,在空气中800℃活化焙烧5h后,发现αFe_2O_3和所加氧化物之间发生了不同的反应,生成不同的化合物。该结果有助于进一步理解这些氧化物作为助剂和载体的作用。It was indicated that when the mixtures, formed by accumulatively adding K2O, Cr2O3, MgO,CuO and SiO2 to a Fe2O3 in turn, were activated at 800cccccccccccccc in atmosphere for 5h, different reactions between a Fe2O3 and the added oxides were caused, and different compounds produced. The result will contribute to a better understanding of the role of various oxides as promoters and supports.
