摘要
采用空气氧化法,以四水合氯化亚铁和氢氧化钠为原料,通过调节反应体系的p H,制备不同形貌的Fe3O4。通过磁性表征,得出形貌与磁性的关系。并在实验中添加不同含量的Zn2+,使其代替Fe3O4的Fe2+,在一定范围使Fe3O4的剩磁、矫顽力可。
In the paper, Fe Cl2·4H2O and Na OH as starting materials, Various morphologies have been successfully synthesized by regulating reaction system＇s p H.The relation between morphology and magnetic properties through characterization. And adding different amount of Zn^2＋ in the experiment, which replaces Fe^2＋of Fe3O4,thereby the remanence and coercivity of Fe3O4 are controllable In a certain range
