Preparation method of high-strength Mn-Zn soft magnetic ferrite core material
The invention discloses a preparation method of a high-strength Mn-Zn soft magnetic ferrite core material. The high-strength Mn-Zn soft magnetic ferrite core material is prepared from the raw materials of Fe2O3, Mn3O4, ZnO, CoO2, SiO2, TiO2, Ta2O5, In2O3, Tb2(CO3)3, BaCO3, V2O5, CuO, CaO, Ga(OH)3, Nd(NO3)3.6H2O, VB2, WC and the like. The high-strength Mn-Zn 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, components of VB2, WC and the like can be used as modifying additives of the high-strength Mn-Zn soft magnetic ferrite core material, not only can the breaking strength of the high-strength Mn-Zn soft magnetic ferrite core material be increased, but also excellent magnetic performance of the high-strength Mn-Zn soft magnetic ferrite core material can be maintained, and higher saturation magnetic flux density, higher magnetic conductivity and lower power consumption are obtained.
