High-Bs low-power-consumption manganese-zinc ferrite material and preparation method thereof

The invention relates to the technical field of ferrite material preparation, in particular to a high-Bs low-power-consumption manganese-zinc ferrite material and a preparation method thereof. The high-Bs low-power-consumption manganese-zinc ferrite material comprises main components and auxiliary components, wherein the main components comprise, by mole, 54 to 55 mol% of Fe2O3, 40 to 41 mol% of Mn3O4 and 4.5 to 5.5 mol% of ZnO; the auxiliary components are prepared from the following main components in percentage by weight: 150 to 200 ppm of SiO2, 100 to 150 ppm of P2O5, 500 to 800 ppm of CaO, 300 to 400 ppm of ZrO2 and 400 to 500 ppm of Nb2O5. The high-Bs low-power-consumption manganese-zinc ferrite material is prepared on the basis that no NiO is added, the production cost is greatly reduced, meanwhile, a unique sintering process is adopted, SiO2 and P2O5 are used as sintering accelerators, the sintering density, magnetic conductivity and Bs of the product are effectively improved,and the power consumption
