Large-scale SQ type manganese zinc ferrite magnetic core and preparation method thereof
The invention discloses a large-scale SQ type manganese zinc ferrite magnetic core which comprises the following raw materials in percentage by weight: 68-70% of Fe2O3, 14-16% of Mn3O4, 14-16% of ZnO,PVA glue and an additive, wherein the weight percentage of the raw materials with the particle size of 60-160 meshes is 80-90%, and the particle sizes of the rest raw materials are greater than 160 meshes. Meanwhile, the invention also discloses a preparation method of the large-scale SQ type manganese zinc ferrite magnetic core. The method comprises the following steps: sintering the raw materials according to a certain temperature curve, and cooling under the condition that the oxygen partial pressure coefficient is 7.5-8, and molding. Under the support of an original dry process productionkey technology, the method is aimed at the production of high frequency, high impedance and low power consumption materials: adopting a good basic formula and additive combination, limiting the suitable sintering atmosphere curve and strict process control and management, and finally producing a new broadband high-impedance material.
本发明公开了一种大型SQ型锰锌铁氧体磁芯，包括以下重量百分比的原料：Fe2O3 68‑70％、Mn3O4 14‑16％、ZnO 14‑16％、PVA胶和添加剂；其中粒径为60‑160目的原料重量百分比为80‑90％，其余原料粒径大于160目。同时，本发明还公开了大型SQ型锰锌铁氧体磁芯的制备方法，包括一定的温度曲线对原料进行烧结后，最后在氧分压系数7.5‑8的条件下降温后成型。本发明在原有干法工艺生产关键技术的支持下，针对高频、高阻抗、低功耗材料进行生产，采用良好的基础配方和添加剂组合相搭配，且限定适合的烧结气氛曲线以及严格的工艺控制与管理，最终制得新的宽频高阻抗材料。
