Manganese-zinc high-permeability high-Curie-temperature high-frequency material and preparation method thereof
The invention discloses a manganese-zinc high-permeability high-Curie-temperature high-frequency magnetic material and a preparation method thereof. The main components of the magnetic material comprise 52.67 mol%-53.43 mol% of Fe2O3 and 16.15 mol%-17.3 mol% of ZnO, with the balance being Mn3O4. The auxiliary components of the magnetic material comprise three or more than three selected from the group consisting of CaCO3, Bi2O3, Nb2O5, MoO3 and SiO2. The magnetic material has a Curie temperature Tc of larger than 180 DEG C, initial magnetic conductivity (25 DEG C, 10 kHz) [mu]i of larger than7000, and magnetic conductivity (25 DEG C, 400 kHz) [mu] of larger than 7000. The magnetic material prepared by the method disclosed by the invention can obtain high magnetic conductivity and high Curie temperature and meets requirements on broadband characteristics; the magnetic conductivity at a low-frequency band and a high-frequency band is always kept at a relatively high level; and the application range of the material is effectively expanded.
本发明公开了一种锰锌高磁导率高居里温度高频磁性材料及其制备方法。该磁性材料主成分包括52.67mol％～53.43mol％的FeO，16.15mol％～17.3mol％的ZnO，其余为MnO；辅助成分包括CaCO、BiO、NbO、MoO、SiO中的三种或三种以上；所述磁性材料的居里温度Tc＞180℃，初始磁导率(25℃,10kHz)μi＞7000，磁导率(25℃,400kHz)μ＞7000。本发明方法制备的磁性材料可以在既获得高磁导率和高居里温度的同时，还具备兼顾宽频特性要求，低频段和高频段的磁导率始终保持在较高的水平，有效扩展了材料的应用范围。
