Preparation method of high-impedance soft magnetic ferrite core material
The invention discloses a preparation method of a high-impedance soft magnetic ferrite core material. The high-impedance soft magnetic ferrite core material is prepared from the raw materials of Fe2O3, MnCO3, ZrO2, Co2O3, HfO2, BaTiO3, TaSi2, Ce2O3, BN, SiO2, V2O5, Li2O, CuO, CaCO3, MgSiO3 and the like. The high-impedance 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. According to the preparation method disclosed by the invention, due to composite addition of the raw materials of ZrO2, HfO2, BaTiO3, TaSi2, Ce2O3, BN, Li2O, MgSiO3 and the like, the electric resistivity of the high-impedance soft magnetic ferrite core material can be increased to a large extent, the high-impedance soft magnetic ferrite core material is enabled to have very high impedance characteristics under both high frequency and low frequency, and higher magnetic conductivity and higher saturation magnetic flux density are obtained.
