Preparation method of high-frequency high-DC (Direct Current) superposition soft magnetic ferrite core material
The invention discloses a preparation method of a high-frequency high-DC (Direct Current) superposition soft magnetic ferrite core material. The high-frequency high-DC superposition soft magnetic ferrite core material is prepared from the raw materials of Fe2O3, MnO, ZnO, Al2O3, CaO, Nb2O5, Sm2O3, GaSb, SiO2, CaO, ZrO2, TiO2, 2CoCO3.3Co(OH)2.H2O, LaB6 and the like. The high-frequency high-DC superposition soft magnetic ferrite core material is prepared by the steps of first burdening, first ball milling, first sintering, second burdening, second ball milling, compression molding, second sintering and the like. The high-frequency high-DC superposition soft magnetic ferrite core material which is prepared by the preparation method disclosed by the invention is excellent in comprehensive performance, not only is lower power consumption obtained under high frequency, but also extremely good DC superposition performance is obtained.
