Broadband high-impedance high-resistivity manganese zinc ferrite material and preparation method thereof
The invention provides a broadband high-impedance high-resistivity manganese zinc ferrite material and a preparation method thereof, and belongs to the technical field of magnetic materials. The manganese zinc ferrite material disclosed by the invention comprises a functional component and an auxiliary component, wherein the functional component is prepared from Fe2O3, MnO and ZnO. By adjusting the preparation method of the manganese-zinc ferrite material, the cracking of the manganese-zinc ferrite material is avoided, and the sintering qualification rate of the product is improved. The manganese-zinc ferrite material prepared by the invention has relatively high resistivity and initial permeability, meanwhile, has excellent broadband impedance characteristic, and can be used in severe working environments such as high frequency, low temperature or high temperature.
本发明提供了一种宽频高阻抗高电阻率锰锌铁氧体材料及其制备方法，属于磁性材料技术领域。本发明的锰锌铁氧体材料包括功能性组分和辅助性组分，其中功能性组分由Fe2O3、MnO和ZnO组成。本发明通过调整锰锌铁氧体材料的制备方法，避免了锰锌铁氧体材料的开裂，提高了产品烧结合格率。本发明制备的锰锌铁氧体材料具有较高的电阻率和初始磁导率，同时宽频阻抗特性优良，能够在高频以及低温或高温等恶劣工作环境下使用。
