Preparation method of ultrahigh-Bs low-loss manganese zinc ferrite material for cloud computing
The invention provides a preparation method of an ultrahigh-Bs low-loss manganese zinc ferrite material for cloud computing. The method comprises the steps of mixing Fe2O3, ZnO and Mn3O4 to obtain a precursor material, mixing the precursor material, water and an adhesive, and carrying out wet ball milling to obtain first slurry; performing spray granulation on the first slurry to obtain a first granular material; pre-sintering the first granular material to obtain a second granular material; mixing the second granular material, water, an adhesive and an additive, and performing wet ball milling to obtain second slurry; performing spray granulation on the second slurry to obtain a third granular material, and pressing the third granular material into an annular magnetic core green body; and carrying out segmented sintering on the annular magnetic core green body. According to the preparation method provided by the embodiment of the invention, the saturation flux density of the manganese zinc ferrite material can be improved, and the loss is reduced.
本申请提供云计算用超高Bs低损耗锰锌铁氧体材料的制备方法，方法包括将Fe2O3、ZnO、Mn3O4进行混合，得到前驱体材料，并将前驱体材料、水及黏合剂混合后进行湿法球磨，得到第一浆料；将第一浆料进行喷雾造粒，得到第一颗粒材料；将第一颗粒材料进行预烧结处理，得到第二颗粒材料；将第二颗粒材料、水、黏合剂与添加剂混合后进行湿法球磨，得到第二浆料；将第二浆料进行喷雾造粒，得到第三颗粒材料，并将第三颗粒材料压制成环形磁芯生坯；将环形磁芯生坯进行分段式烧结。本申请实施例提供的制备方法，可以提高锰锌铁氧体材料的饱和磁感应强度，并降低损耗。
