Low-cost permanent magnet barium ferrite and preparation method thereof
The invention relates to a low-cost permanent magnetic barium ferrite and a preparation method thereof, the chemical formula of the permanent magnetic ferrite is Ba1-x-yCaxSryFe2nO19, in the formula, 0.03 < = x < = 0.2, 0.03 < = y < = 0.2, and 5.6 < = n < = 6.0. The preparation raw material of the permanent magnetic barium ferrite is low-cost iron scale, the permanent magnetic ferrite is prepared by pretreating the iron scale, and the total purity of the pretreated oxide is greater than or equal to 99.2%. The raw materials selected for preparation of the permanent magnet barium ferrite are low in price, the prepared permanent magnet barium ferrite still has good permanent magnet performance, and the preparation method is simple in process and low in production cost.
一种低成本永磁钡铁氧体及其制备方法，该永磁铁氧体的化学式为Ba1‑x‑yCaxSryFe2nO19，式中0.03≤x≤0.2，0.03≤y≤0.2，5.6≤n≤6.0。该永磁钡铁氧体制备原材料选用低成本铁鳞，通过对铁鳞预处理制备永磁铁氧体，预处理后氧化物总纯度≥99.2％。本发明永磁钡铁氧体制备选用的原材料价格低，而所制得的永磁钡铁氧体仍然具有较好的永磁性能，其制备方法工艺简单，生产成本低。
