Preparation method of permanent magnetic ferrite
The invention discloses a preparation method of permanent magnetic ferrite, and belongs to the technical field of magnetic materials, the preparation method comprises the following steps: fully mixing high-chlorine iron oxide red and solvent water in proportion to obtain slurry, adding a pH value regulator while stirring to carry out condensation polymerization, and curing and polymerizing to obtain slurry; adding an alkaline solvent while stirring, precipitating, and draining to obtain slurry; the preparation method comprises the following steps: proportioning raw materials according to a molecular formula, calculating the weight of actually required iron oxide red slurry, weighing the required weight of the slurry through a weighing tank, mixing the slurry with other materials, and adding a dispersing agent; crushing the obtained slurry through crushing equipment, concentrating, and pre-sintering the concentrated slurry through a rotary kiln to obtain ferrite pre-sintered granules; crushing the pre-sintered granules through a dry ball mill, adding water and an additive, carrying out secondary ball milling, and continuously carrying out ball milling to obtain 250-mesh slurry; concentrating the obtained slurry, and performing compression molding in a magnetic field; and carrying out heat preservation on the molded body at 350 DEG C for 3-4 hours, removing water and glue, and sintering in air to obtain the permanent magnetic ferrite.
本发明公开了一种永磁铁氧体的制备方法，属于磁性材料技术领域，将高氯铁红与溶剂水按比例充分混合得到料浆，搅拌下加入pH值调节剂进行缩聚反应，经熟化聚合得料浆；在搅拌下加入碱性溶剂后，进行沉淀、排水，得到料浆；将原材料按分子式进行配比，计算实际所需铁红料浆重量，通过称重罐称取所需料浆重量后与其他物料混合，并加入分散剂；将所得料浆通过解碎设备进行解碎，再浓缩，将浓浆通过回转窑预烧，得到铁氧体预烧颗粒料；将所得预烧颗粒料经干式球磨粉碎后，并加入水、添加剂进行二次球磨，连续球磨得到250目的料浆；再将所得料浆浓缩后在磁场下压制成型；将成型体在350℃下保温3‑4小时除水排胶后，在空气中烧结，得到永磁铁氧体。
