以氧化铁废料、Fe2O3粉和Al2O3粉为原料，分别采用烧结法和电铸法合成铁铝尖晶石，用X射线衍射（XRD）分析了合成产物的物相组成，用扫描电子显微镜（SEM）观察其微观结构实验结果表明，在试样中加入石墨，采用包碳法，可获得还原气氛，铁铝尖晶石烧结法合成的硅含量只有20%，而电铸法合成的硅含量达到97%以上。
In this work,hercynite was synthesized from iron oxide scrap,Fe2O3 powder and Al2O3 powder by sintering process and electrocast process,respectively.The phase constituents of synthesized product were analyzed by X-ray diffraction(XRD),and the microstructure was observed with scanning electron microscopy(SEM).The experimental results show that the reducting stmosphere was obtained by adding of graphite in the samples and by embedding carbon method.The hercynite content synthesized by sintering process has only 20% and electrocast method arrives above 97%.
