Problems solved by technology

Although many ferrite core materials in the current technology have high initial magnetic permeability, the wide temperature characteristics of magnetic permeability are very general, and it is difficult to maintain high magnetic permeability under various ambient temperatures; Although some products can achieve better magnetic permeability and wide temperature characteristics, the preparation cost is too high, the preparation process is cumbersome, and it is not easy to operate
Prior art CN105084882A discloses that related nickel-ferrite system is used to improve the magnetic permeability and functional loss of soft ferrite materials, but it does not involve the improvement of power consumption level for high-frequency materials, and the improvement effect is limited

Abstract

The invention discloses a high frequency manganese-zinc soft magnetic ferrite material and a preparation method and applications thereof. The high frequency material comprises a main component and anauxiliary component; the main component comprises Fe2O3, MnO, ZnO, and NiO; and the auxiliary component comprises Ca2CO3, V2O5, Nb2O5, K2CO3, Co2O3, and SnO2. By introducing nickel(II) oxide into themain formula, a quaternary formula system is formed, namely a nickel zinc ferrite system is added into a manganese-zinc ferrite system, the grain size and resistance can be well controlled, thus the high frequency loss is reduced, the high frequency material has a high saturation flux density and a high Curie temperature and is suitable for being used in a high frequency environment (500 KHz to 1MHz). By controlling the pre-burning temperature, sintering temperature, and particle size of powder, the saturation flux density is increased, and the functional loss is reduced.
