羰基多晶铁纤维合成CoZn-W铁氧体研究

Synthesis of CoZn-W-type Hexagonal Ferrite with Carbonyl Iron Fiber

以羰基多晶铁纤维作为铁源取代传统的FeOOH原料，用化学沉淀一局部规整法制备了CoZn—W铁氧体。XRD、VSM和SEM分析结果表明，CoZn—W中无杂相出现其颗粒呈块状或长块状，颗粒尺寸约2～12μm。其饱和磁化强度胁为70．90emu·g^-1，矫顽力强度胁为108．620e。

Using carbonyl iron fiber as raw materials to replace the traditional FeOOH, CoZn-W type ferrite precursor was prepared by precipitation-toptactic reaction method. The synthesized CoZn-Wwas pure phase without impurity, appeared block or long block mor- phology with particle size of 2 - 12μm, and thus presented the saturation magnetization （Ms） ofT0.90 emu.g-1 ,and coercive force （Hc） of 108.62 Oe.
