Manganese-zinc ferrite magnetic material with high magnetic inductivity and preparation method thereof
The invention belongs to the technical field of manganese-zinc ferrite magnetic materials, and particularly relates to a manganese-zinc ferrite magnetic material with high magnetic inductivity and a preparation method thereof. The material comprises a main material component and an additive component. The main material component comprises the following components in percentage by mass: 60%-68% of Fe2O3, 23%-30% of MnO and 5%-9% of ZnO. The additive component comprises the following components in percentage by mass: in terms of the total mass of the main material component: 0.020%-0.035% of CaCO3, 0.005%-0.015% of SiO2, 0.01%-0.02% of Bi2O3, 0.01%-0.02% of MoO3 and 0.02%-0.03% of P2O5. A manganese-zinc ferrite sample material is obtained through primary sanding, primary spray granulation, presintering, secondary sanding, secondary spray granulation, profiling and sintering; and the magnetic conductivity of the material is improved, and the comprehensive performance of the material is enhanced.
