Ultra-low-loss high-Bs wide-temperature broadband manganese zinc ferrite material and preparation method thereof
The invention discloses an ultralow-loss high-Bs wide-temperature broadband manganese-zinc ferrite material and a preparation method thereof, and particularly relates to the technical field of soft magnetic ferrite materials, the ultralow-loss high-Bs wide-temperature broadband manganese-zinc ferrite material comprises main ingredients and auxiliary ingredients, the main ingredients comprise Fe2O3, ZnO and the balance of Mn3O4 according to molar percentage, and the auxiliary ingredients comprise CaO, SiO2, Nb2O5, Co2O3, TiO2, SnO2, ZrO2, V2O5, MoO3 and CuO. The invention also provides a preparation method of the ferrite, and the ferrite has the main characteristics of low-melting-point substance doping, low-temperature sintering, multi-stage pre-sintering and rapid heating, so that the internal resistivity of the soft magnetic ferrite material can be effectively improved, the eddy-current loss of the magnetic core material in the use process is reduced, and the service life of the magnetic core material is prolonged. And the density, saturation flux density and magnetic flux of the material are increased, so that the product has higher sintering density and higher Bs characteristic.
