Ultrahigh saturation flux density manganese-zinc ferrite material and preparation method thereof
The invention discloses an ultrahigh saturation magnetic flux density manganese-zinc ferrite material, which is composed of a main component and an auxiliary component. The main component is composedof 55.25-56.25 mol% of Fe2O3, 2.5-3.5 mol% of ZnO, 0.10-0.20 mol% of Co2O3 and the balance of MnO in terms of oxide; and the auxiliary component includes 0.01-0.06 wt% of Nb2O5, 0.05-0.15 wt% of CaCO3, 0-0.05 wt% of NiO, 0.01-0.04 wt% of V2O5, 0-0.01 wt% of SiO2, 0-0.05 wt% of TiO2 and 0-0.05 wt% of Ta2O5. The manganese-zinc ferrite material prepared by the invention has the power consumption of less than 250kW/m<3> at the temperature of 25 DEG C and 100 DEG C under 3MHz and 30mT, and the saturation flux density at the temperature of 100 DEG C reaches 460 mT or above, so that the manganese-zinc ferrite material adapts to the requirements of a high-frequency transformer and a server inductor.
