The high-performance molybdenum-based rare-earth ferrite magnetic core material comprises the following raw materials in parts by weight: 5 parts of ferric sulfide, 11 parts of ferric sulfate, 15 parts of potassiummolybdate, 27 parts of ferric oxide, 21 parts of ferroferric oxide, 5 parts of lanthanum chloride, 9 parts of copper hydroxide, 2 parts of zinc carbonate, 7 parts of manganese dioxide, 2 parts of bentonite, 13 parts of zirconium dioxide, 11 parts of titanium tetrachloride and 8 parts of molybdenum trioxide.

Description

technical field [0001] The application belongs to the field of magnetic core material manufacturing, in particular to a preparation method of a high-performance molybdenum-based rare earth ferrite magnetic core material. Background technique [0002] Ferrite cores are mainly composed of three metal elements: iron (Fe), manganese (Mn), and zinc (Zn), and are usually called manganese-zinc ferrite. Toroidal ferrite cores have a high magnetic effect because they have no air gap and have a uniform cross-sectional area. However, it is difficult for many ferrite core materials in the current technology to maintain a high and stable magnetic permeability under various ambient temperatures. Although some products can achieve better magnetic permeability wide temperature characteristics, but The preparation cost is too high, the preparation process is cumbersome and difficult to operate. Contents of the invention [0003] In order to solve the above technical problems, the applica...
