Calcium series permanent magnetic ferrite material and preparation method thereof
The invention belongs to the technical field of permanent magnetic ferrite materials, and discloses a calcium series permanent magnetic ferrite material and a preparation method thereof. The calcium series permanent magnetic ferrite material is CaASr<1-x-y>Fe<2n-z>Co O<19>, wherein A must comprise La and Y, x is greater than or equal to 0.3 and less than or equal to 0.6, y is greater than or equal to 0.2 and less than or equal to 0.5, z is greater than or equal to 0.25 and less than or equal to 0.45, n is greater than or equal to 4.9 and less than or equal to 5.7, and raw materials are derived from La (OH) 3, Y2O3, Co2O3, Fe2O3, SrCO3 and CaCO3. According to the invention, through graded ball milling, secondary addition of iron red and direct primary addition of lanthanum hydroxide instead of lanthanum oxide, the obtained calcium series permanent magnetic ferrite material obviously improves and enhances the magnetic performance and the magnetic flux density of the working surface of a tile body.
本发明属于永磁铁氧体材料技术领域，公开了一种钙系永磁铁氧体材料及其制备方法。该钙系永磁铁氧体材料成分包括CayAxSr1‑x‑yFe2n‑zCozO19，其中，A必须包含La和Y，0.3≤x≤0.6，0.2≤y≤0.5，0.25≤z≤0.45，4.9≤n≤5.7，原料来源于La(OH)3、Y2O3、Co2O3、Fe2O3、SrCO3和CaCO3。本发明通过分级球磨，二次添加铁红以及采用氢氧化镧代替氧化镧直接一次加入，所得钙系永磁铁氧体材料对磁性能和瓦体工作面的磁通密度都有明显改善和提高。
