摘要 在不使用表面活性剂的条件下,以K3Fe(CN)6为铁源,采用溶剂热合成技术,于200℃反应24h得到亚微球状的Fe3O4.产物的物相、微观形貌、结构和表面元素状态分别采用X射线衍射仪、场发射扫描电子显微镜、透射电子显微镜和X射线光电子能谱等进行了表征.结果表明,产物为面心立方结构、具有单分散性的Fe3O4亚微球,平均直径为170nm.通过一系列对比实验研究了反应参数对产物的影响,发现作为还原剂和溶剂的乙二醇在合成中起着关键的作用;此外,反应时间和反应温度也对最终产物产生重要影响.所得近单分散的Fe3O4亚微球在室温条件下的磁滞回线表现出铁磁行为,其饱和磁化率为60.8emu/g,矫顽力为124.7Oe.
