Permanent magnetic ferrite material as well as preparation method and application thereof
The invention belongs to the field of magnetic materials. The invention provides a permanent magnetic ferrite material as well as a preparation method and application thereof, the preparation method is characterized in that a small amount of ferrite powder is added into a permanent magnetic ferrite raw material as a crystallization seed, so that the solid-phase reaction is accelerated, the pre-sintering temperature is reduced, and the high-performance permanent magnetic ferrite material is prepared without adding lanthanum and cobalt; ferrite crystal particles in the obtained permanent magnetic ferrite material are more uniform, so that generation of coarse crystal particles is effectively avoided, and the comprehensive magnetic performance of the permanent magnetic ferrite material is obviously superior to that of similar materials prepared by a traditional process.
本发明属于磁性材料领域。本发明提供了一种永磁铁氧体材料及其制备方法与用途，所述制备方法通过向永磁铁氧体原料中添加少量铁氧体粉末作为结晶种子，从而加速固相反应，降低预烧温度，制备出高性能永磁铁氧体材料，而无需镧钴的添加；所得永磁铁氧体材料中铁氧体结晶颗粒更均匀，因有效避免了粗大结晶颗粒的产生，其综合磁性能明显优于传统工艺制备的同类材料。
