Preparation method of soft magnetic ferrite material
The invention provides a preparation method of a soft magnetic ferrite material, which comprises the following steps: S1, primary ball milling of a main material: grinding the main material in a ball mill to a micron level, drying, and cooling to room temperature; s2, pre-sintering: pre-sintering the cooled main material for a period of time, taking out, cooling, and blending with the auxiliary material; s3, secondary ball milling: putting the mixed main material and auxiliary material into a ball mill for secondary ball milling, and drying to obtain a pre-sintered mixture; and S4, mixing and grinding: grinding the pre-sintered mixture in a ball mill, drying after grinding, granulating, pressing, sintering and molding to obtain the target soft magnetic ferrite material. The invention provides the preparation method of the soft magnetic ferrite material with high saturation magnetic flux density and excellent magnetic performance.
本发明提供一种软磁铁氧体材料的制备方法，包括以下步骤：步骤S1：主料一次球磨：将主料在球磨机中研磨至微米级，烘干后冷却至室温；步骤S2：预烧结：将冷却好的主料预烧结一段时间，取出后冷却与辅料共混；步骤S3：二次球磨：将混合好的主料与辅料置入球磨机中二次球磨，烘干后得到预烧结混合料；步骤S4：混合研磨：将预烧结混合料置入球磨机中研磨，研磨后烘干后造粒、压制、烧结成型，即得目标软磁铁氧体材料。本发明提供一种饱和磁通密度高、磁性能优异的软磁铁氧体材料的制备方法。
