High-broadband low-loss ferrite magnetic material and preparation method thereof
The invention discloses a high-broadband low-loss ferrite magnetic material, and relates to the technical field of materials. The high and broadband low-loss ferrite magnetic material is prepared from the following raw materials in parts by weight: 65 to 71 parts of Fe2O3, 3 to 7 parts of ZnO, 0.2 to 0.4 part of Co3O4, 0.2 to 0.4 part of SnO2, 0.01 to 0.05 part of SiO2 and the balance of Mn3O4. According to the invention, the traditional ternary manganese-zinc ferrite is broken through as a main cost, and the main component is increased to MnZnCoSnSi six-element. The grinding time is prolonged to 4-7 hours by adopting superhard steel balls and utilizing an overspeed ball mill, so that the average particle size of the ground material is less than 0.85 microns, and the activity of a solid-phase reaction during sintering is improved.
本发明公开了一种高、宽频低损耗铁氧体磁性材料，涉及材料技术领域；该高、宽频低损耗铁氧体磁性材料包括下列重量份的原料组成：65‑71份的Fe2O3、3‑7份的ZnO、0.2‑0.4份的Co3O4、0.2‑0.4份的SnO2、0.01‑0.05份的SiO2、余量为Mn3O4。本发明打破传统三元锰锌铁氧体为主成本，将主成分增加到MnZnCoSnSi六元。采用超硬钢球利用超速球磨机加长研磨时间至4‑7小时，使得研磨后物料的平均粒径小于0.85微米，增加烧结时固相反应的活性。
