| 摘 要： | 自行开发的添加剂,应用到碱法制备α-FeOOH的反应体系中,能抑制晶体枝杈的生长、控制晶体形态。以此α-FeOOH为原料加工成的γ-Fe_2O_3磁粉,具有高的饱和磁化强度。加入量为10ppm时,σ_s为79A·m~2·kg~(-1)上下;当加入量为20ppm时,σ_s可达84.93A·m~2·kg~(-1)。

| Abstract: | γ-FeooH was prepared by the alkaline method through adding a salf-developed additive agent, Which can effectively hold back the growth of branch-shaped defect in Crystal and control the form of prepared crystal. The final production of ?-Fe2O3 prepared from γ-FeooH has a high Saturation magnetization,Which is 79A When it is 20PPM |
