Preparation method of manganese-zinc ferrite material with high saturation flux density and low loss
The invention discloses a preparation method of a manganese-zinc ferrite material with high saturation flux density and low loss. The preparation method comprises the following steps of: S1, weighingmain materials including Fe2O3, MnO and ZnO according to a certain molar percentage formula; S2, adding water into the main materials, carrying out ball milling, drying, and carrying out heat preservation and presintering to obtain a presintered material; S3, weighing a proper amount of CaCO3, TiO2, Nb2O5 and Bi2O3 based on the weight of the presintered material, uniformly mixing the weighed materials with the presintered material, adding water, and carrying out ball milling to obtain a mixture; S4, uniformly mixing the mixture with a binder, granulating, and carrying out compression molding to obtain a blank; and S5, carrying out heat preservation sintering on the blank to obtain the manganese-zinc ferrite material with high saturation flux density and low loss. The manganese-zinc ferritematerial prepared by the invention has high saturation flux density, low loss and excellent magnetic performance.
本发明公开了一种高饱和磁感应强度低损耗锰锌铁氧体材料的制备方法，包括以下步骤：S1、按一定摩尔百分比的配方称取主料：Fe2O3、MnO、ZnO；S2、将主料加水球磨后烘干，进行保温预烧，得到预烧料；S3、以预烧料的重量为基准，称取适量CaCO3、TiO2、Nb2O5、Bi2O3,与预烧料混合均匀后加水球磨，得到混合料；S4、将混合料与粘结剂混合均匀，然后造粒、压制成型，得到坯料；S5、将坯料进行保温烧结，得到高饱和磁感应强度低损耗锰锌铁氧体材料。本发明制得的锰锌铁氧体材料具有高饱和磁感应强度和低损耗，磁性能优良。
