Abstract: The invention describes a method of preparing magnetic ferrites from layered precursors in which Fe2+ is first introduced into the layers of layered double hydroxides (LDHs) in order to prepare Me-Fe2+—Fe3+ LDHs, and then by utilizing the easily oxidized nature of Fe2+, binary or multi-component ferrite materials containing Fe3+ in a single crystalline phase can be prepared. Values of the saturation magnetization of ferrites prepared by the method are significantly increased compared with ferrites prepared by traditional methods. Because the metal elements in the layered precursor have the characteristics of a high degree of dispersion, high activity and small particle size (average particle size 40-200 nm), no milling is required before calcination, thus simplifying the production process, shortening the production period, reducing capital investment in equipment and economizing on energy costs. In addition, the method does not corrode production equipment and does not pollute the environment.

Abstract translation: 本发明描述了一种从层状前体制备磁性铁氧体的方法，其中Fe 2+ 2首先被引入层状双氢氧化物（LDH）层中以制备Me-Fe 2+， / Fe 3+ LDH，然后通过利用Fe 2+的易氧化性质，含Fe 3+的二元或多组分铁素体材料， 可以制备单晶相中的。 通过该方法制备的铁氧体的饱和磁化强度与通过传统方法制备的铁氧体相比显着增加。 由于层状前体中的金属元素具有高分散性，高活性，小粒径（平均粒径40〜200nm）的特征，因此在煅烧前不需要研磨，因此简化了制造工序，缩短了生产 减少设备资金投入，节约能源成本。 此外，该方法不会腐蚀生产设备，也不会污染环境。
