High-performance permanent magnetic ferrite and preparation method thereof
The invention relates to a high-performance permanent magnetic ferrite and a preparation method thereof. The high-performance permanent magnetic ferrite comprises the following components: 4-18 wt% of lanthanum-cerium-neodymium-iron-boron magnetic powder; 1.1 to 1.6 wt% of solid camphor; 0.25 to 0.35 wt% of calcium stearate; and the balance of strontium-barium ferrite dry-pressed anisotropic powder. The method has the beneficial effects that the product is high in magnetic performance and low in production cost, the application range of the product is expanded, and rare earth resources are saved. The preparation method of the product is simple and convenient in process, the prepared product is good in consistency and high in percent of pass, and the service life of the product can be effectively guaranteed.
一种高性能永磁铁氧体及其制备方法，所述高性能永磁铁氧体包括以下组分：镧铈钕铁硼磁粉4～18wt%；固体樟脑1.1～1.6wt%；硬脂酸钙0.25～0.35wt%；余量为锶钡铁氧体干压异性粉料。有益效果是，产品磁性能高、生产成本低，扩大了产品应用范围，并节约了稀土资源。该产品的制备方法，其工艺简单、方便，制备得到的产品一致性好、合格率高，且可有效保证产品的使用寿命。
