Wide-temperature high-frequency low-loss soft magnetic ferrite material and preparation method thereof
The invention discloses a wide-temperature high-frequency low-loss soft magnetic ferrite material, which is prepared from the following components in percentage by mass: 69.0 to 72.0 weight percent of Fe2O3, 6.0 to 7.5 weight percent of ZnO, 20.5 to 24 weight percent of MnO, 0.40 to 0.66 weight percent of an auxiliary material and 0.10 to 0.32 weight percent of an additive, the auxiliary material is a mixture of CaCO, Co2O3 and Nb2O5, and the auxiliary material is prepared from the following components in percentage by mass: 0.02 to 0.06 weight percent of CaCO, 0.35 to 0.55 weight percent of Co2O3 and 0.03 to 0.05 weight percent of Nb2O5. According to the invention, by adding corresponding auxiliary materials and additives into the soft magnetic ferrite material, the situation that the soft magnetic ferrite material is influenced by external temperature in the use process and the fluctuation of wire permeability and loss is large is obviously reduced, and the stability of the soft magnetic ferrite material in the use process is improved; meanwhile, the effect of grinding and smashing the raw materials of the soft magnetic ferrite material is improved, the production quality of the soft magnetic ferrite material is improved, and the risk that the soft magnetic ferrite material is damaged due to environmental influence in the using process is reduced.
