High-magnetic-permeability low-loss soft-magnetic ferrite material and preparation method
The invention discloses a high-magnetic-permeability low-loss soft-magnetic ferrite material. Raw materials of the material comprises, in parts by weight, 100 parts of main compositions, 0.5-1 part of auxiliary compositions, and 1-5 parts of auxiliary agents. The raw materials of the main compositions comprise, in parts by substance amount, 20-30 parts of Fe3O4, 15-18 parts of NiO, 10-13 parts of ZnO, 2-4 parts of CuO, 6-8 parts of V2O5 , and 1-2 parts of WO3; the raw materials of the auxiliary compositions comprise, in parts by weight, 1-2 parts of Bi2O3, 0.5-1.5 parts of SiO2, 1-3 parts of Nb2O5, 1-4 parts of Ti2O3, 2-5 parts of PtO2, and 1-2 parts of chromium boride; and the raw materials of the auxiliary agents comprise, in parts by weight, 100 parts of modified polyvinyl alcohol, 5-10 parts of polyvinyl alcohol, 1-4 parts of barium sulfate, 1-2 parts of magnesium stearate, and 1-5 parts of zinc stearate. The invention also discloses a preparation method of the high-magnetic-permeability low-loss soft-magnetic ferrite material. The material possesses high frequency, high magnetic permeability, high electrical resistivity and low loss, and the preparation technology is simple.
