High-power nickel-zinc soft magnetic ferrite material and preparation method thereof
The invention discloses a high-power nickel-zinc soft magnetic ferrite material and a preparation method thereof. The preparation method comprises the following steps: mixing S1, Fe2O3, NiO and ZnO tobe uniform to obtain a main material, carrying out primary ball milling and drying on the main material, and obtaining a pre-sintered material through pre-sintering treatment and crushing; S2, uniformly mixing CuO, V205, MoO3, CoC2O4 and Gd2O3 to obtain an auxiliary material, uniformly mixing the auxiliary material with the pre-sintered material, and carrying out secondary ball milling and dryingto obtain a mixture; S3, uniformly mixing the mixture with a polyvinyl alcohol aqueous solution to obtain mixed slurry; S4, performing stirring treatment on the mixed slurry under a microwave condition, and then performing spray granulation to obtain a granular material; and S5, carrying out compression molding on the granular material, then carrying out high-temperature sintering, and performingcooling to obtain the ferrite material. The nickel-zinc soft magnetic ferrite material prepared by the invention has high saturation flux density and low power loss, and is suitable for being appliedin a high-frequency high-power state.
本发明公开了一种大功率镍锌软磁铁氧体材料及其制备方法，其制备方法包括以下步骤：S1、将FeO、NiO、ZnO混合均匀，得到主料，将主料经过一次球磨后烘干，经过预烧处理、破碎得到预烧料；S2、将CuO、V0、MoO、CoCO、GdO混合均匀，得到辅料，将辅料与预烧料混合均匀，经过二次球磨后烘干，得到混合料；S3、将混合料与聚乙烯醇水溶液混合均匀，得到混合浆料；S4、将混合浆料在微波条件下进行搅拌处理，然后喷雾造粒，得到颗粒料；S5、将颗粒料压制成型，然后高温烧结，冷却后得到铁氧体材料。本发明制备的镍锌软磁铁氧体材料具有高饱和磁感应强度、低功率损耗，适合在高频大功率状态下应用。
