摘　　要：提出了一种合成铁酸锌纳米粉体的新方法。以二价铁盐为原料，用过氧化氢快速氧化得到氢氧化氧铁（δ-FeOOH）；添加计算量的锌离子经沸腾回流制备出纳米级铁酸锌粉体。利用透射电镜（TEM）、X射线衍射（XRD）、振动样品磁强计（VSM）等手段对产物的形貌、谱学性质、磁学性质等进行了研究。结果表明：该方法制备的铁酸锌微粒的粒径在5～20nm，颗粒形貌为球形且具有超顺磁性。A new method for the preparation of nano - sized zinc ferrite （ ZnFe2O4 particles was put forward. This method used ferrous salt as the raw material to prepare δ - FeOOH by quick oxidation of hydrogen peroxide. Adding the cal- culated amount of zinc ion, the nano - sized zinc ferrite particles were prepared under boiling reflux conditions. Morphology, spectroscopic and magnetic properties of the samples were investigated by XRD, TEM and VSM etc.. Results showed that the prepared zinc ferrite particles are spherical and has good superparamagnetism. The size of the particles is in the range of 5 to 20 nm.
