Permanent magnetic ferrite magnetic powder and preparation method thereof
The invention provides permanent magnetic ferrite magnetic powder and a preparation method thereof, the chemical composition of the permanent magnetic ferrite magnetic powder is (BamSr1-m) 1-xLaxFe2n-yMnyO19, m is more than or equal to 0 and less than or equal to 0.5, x is more than 0 and less than or equal to 0.4, y is more than 0 and less than or equal to 0.4, and n is more than or equal to 5.8 and less than or equal to 6. On the premise that the cost is controllable, the intrinsic magnetic performance is influenced through combined substitution, so that the magnet performance is changed, the high-performance permanent magnetic ferrite magnetic powder with high residual magnetism, high coercive force and high rectangularity is obtained, and the magnetic powder has extremely high potential value and can meet the requirements of existing products.
本发明提供一种永磁铁氧体磁粉及其制备方法，所述永磁铁氧体磁粉的化学组成为(BamSr1‑m)1‑xLaxFe2n‑yMnyO19，其中，0≤m≤0.5，0＜x≤0.4，0＜y≤0.4，5.8≤n≤6。本发明在成本可控的前提下，通过联合替代影响内禀磁性能，从而改变磁体性能，获得了一种高剩磁、高矫顽力和高矩形度的高性能永磁铁氧体磁粉，该磁粉具有极高的潜在价值，可以满足现有产品的需求。
