Ultrahigh-permeability soft magnetic ferrite material, magnetic glue and common-mode inductor
The invention discloses an ultrahigh-magnetic-conductivity soft magnetic ferrite material, magnetic glue and a common-mode inductor, and belongs to the technical field of soft magnetic ferrite electronic information materials.The ultrahigh-magnetic-conductivity soft magnetic ferrite material comprises a main component, a doping component and the balance CuO; the main components comprise Fe2O3, ZnO and NiO; the doping component is prepared from the following components in percentage by mass: 0.06 percent to 0.1 percent of MoO3, 0.01 percent to 0.04 percent of CaCO3, 0.03 percent to 0.07 percent of V2O5 and 0.02 percent to 0.07 percent of Nb2O5; the preparation method of the material comprises the following steps: uniformly mixing the powder raw materials of the main components to obtain a mixture A; then presintering the mixture A at 910 +/-30 DEG C to obtain a material B; adding a doping component into the material B, and uniformly mixing to obtain a mixture C; and finally, sintering the mixture C at the temperature of 1,160 +/-30 DEG C to obtain the soft magnetic ferrite material with ultrahigh magnetic permeability. The soft magnetic ferrite material with the ultrahigh magnetic permeability not only has high initial magnetic permeability, but also has higher Curie temperature, and can meet the use requirements of miniaturization, high sensitivity and wide temperature range of inductive devices.
