Manganese zinc ferrite broadband material KAH150 material with high magnetic conductivity and preparation method thereof
The embodiment of the invention discloses a high-magnetic-conductivity manganese zinc ferrite broadband material KAH150 and a preparation method thereof, and the magnetic conductivity ui of the material is in the range of 10000-15000 +/-25% under the frequency condition of 10-200 KHZ; the Curie temperature Tc of the material is greater than 130 DEG C; the method comprises the following steps: obtaining raw materials according to a proportion mode of 51.2 to 54.5 mol percent of Fe2O3, 19.1 to 22.40 mol percent of ZnO and the balance of MnO; the raw materials are sequentially subjected to ball milling, pre-sintering, secondary sanding, spray granulation, blank preparation and sintering treatment, and the high-permeability manganese zinc ferrite broadband material KAH150 material is obtained. And through combined adjustment of a fixed formula and doping, the magnetic conductivity ui of the material can be kept to be greater than or equal to 10000 when the magnetic conductivity is 200KHZ, and the high-frequency performance is greatly improved.
本发明实施例公开了高磁导率锰锌铁氧体宽频材料KAH150材料及其制备方法，所述材料在10‑200KHZ频率条件下，磁导率ui在10000‑15000±25％范围；所述材料的居里温度Tc＞130℃；所述方法包括：按照Fe2O3为51.2‑54.5mol％，ZnO为19.1‑22.40mol％，其余为MnO的配比方式获取原材料；对所述原材料依次进行球磨、预烧、二次砂磨、喷雾造粒、制备毛坯和烧结处理，得到所述高磁导率锰锌铁氧体宽频材料KAH150材料。通过固定配方和掺杂的组合调整，使得材料磁导率在200KHZ时还能保持ui≥10000，高频性能得到大幅改善。
