Preparation method of soft magnetic ferrite core material with high permeability
The invention discloses a preparation method of a soft magnetic ferrite core material with high permeability. The soft magnetic ferrite core material is formed by the raw materials such as Fe2O3, Mn3O4, ZnO, Al2O3, NiO, CaO, ThO2, Y2O3, BaCO3, SrCO3, CuO, Bi2O3, MgO, Rb2O, TaSe2 and B6Si. The material is prepared by the following steps of primary batching, primary ball milling, primary sintering, secondary batching, secondary ball milling, compression moulding, secondary sintering and the like. The soft magnetic ferrite core material prepared by the invention has better combination property, not only has higher permeability with the initial permeability mui being larger than or equal to 15,000 and the maximum permeability mumax being larger than or equal to 24,000, but also has the characteristics of high saturation flux density, low loss, high electrical resistivity, good high temperature stability and the like. The preparation method of the soft magnetic ferrite core material with high permeability is simple in production process, high in yield, low in production cost and suitable to be applied and popularized in large scale.
