The invention relates to the field of magnetic materials, and discloses a method for preparing permanent magnetic ferrite from high-chlorine iron red, and the permanent magnetic ferrite. The method comprises the steps of a, iron red pretreatment; b, chlorine removal; c, preparation of a pre-sintering raw material SrO.MFe2O3; d, pre-sintering; e, secondary grinding; and f, sintering and the like. According to the above scheme, the high-chlorine iron oxide red is adopted as the raw material, so the raw material source of the ferrite permanent magnet is widened; the preparation method is simple and is suitable for large-scale production; and a preparation process is green and environment-friendly, and product performance is stable.
本发明涉及磁性材料领域,公开了一种高氯铁红制备永磁铁氧体的方法及永磁铁氧体,包括:a)铁红预处理、b)除氯、c)制备预烧原料SrO.MFe2O3、d)预烧、e)二次研磨和f)烧结等步骤。本发明方案采用高氯铁红为原料,拓宽了铁氧体永磁体的原料来源;制备方法简单,能够适用于大规模生产;制备过程绿色环保,产品性能稳定。
