Preparation method of wide-frequency magnetic core material with soft magnetic ferrite
The invention discloses a preparation method of a wide-frequency magnetic core material with soft magnetic ferrite. The wide-frequency magnetic core material with the soft magnetic ferrite is prepared from raw materials such as Fe2O3, MnO, ZnO, BaO, CuO, TeO3, Li2CO3, Ce2(CO3)3, ThSiO4, SrAl2O4, Mo2O3, CaO, SiO2, Co2O3, Nb2O5 and MgCO3. The wide-frequency magnetic core material is prepared by performing the steps of preliminary burdening, preliminary ball grinding, preliminary sintering, secondary burdening, secondary ball grinding, pressing forming, secondary sintering and the like. The magnetic core material with the soft magnetic ferrite has the characteristics of high cutoff frequency and wide application frequency range, and is higher in magnetic conductivity and lower in loss factor in a wide frequency.
