High performance soft magnetic ferrite material and preparation method thereof
The invention discloses a high performance soft magnetic ferrite material. The high performance soft magnetic ferrite material comprises, by weight, 100 parts of main components, 0.001-0.003 parts of auxiliary components and 1-5 parts of assistants. The main components comprise, by mole, 40-50 parts of Fe3O4, 16-20 parts of NiO, 15-20 parts of ZnO, 1-3 parts of CuO, 5-10 parts of MnO2 and 1-2 parts of WO3. The auxiliary components comprises, by weight, 0.5-2 parts of Nb2O5, 1-2 parts of SiO2, 0.5-1.5 parts of Co2O3, 0.5-1.5 parts of Ti2O3, 1-3 parts of La2O3 and 1.5-2.5 parts of chromium boride. The assistants comprise, by weight, 100 parts of modified polyvinyl alcohol, 3-6 parts of polyvinyl butyral, 1-3 parts of barium sulfate, 0.5-1.5 parts of silicone emulsion and 1-3 parts of zinc stearate. The invention also discloses a preparation method of the high performance soft magnetic ferrite material. The preparation method has the advantages of high frequency, high magnetic permeability, high resistivity and simple preparation processes.
