The stable ferrite magnetic core material comprises thefollowing raw materials in parts by weight: 15 parts of ferric chloride, 7 parts of ferric sulfate, 5 parts of sodium tungstate, 21 parts of ferric nitrate, 35 parts of ferric oxide, 25 parts of ferroferric oxide, 5 parts of red mud, 2 parts of zinc oxide, 11 parts of copper oxide, 9 parts of zirconium hydroxide and 1 part of titanium tetrachloride.

Description

technical field [0001] The application belongs to the field of magnetic core material manufacturing, in particular to a high-stability ferrite magnetic core material and a preparation method thereof. Background technique [0002] The magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures, which is widely used in coils and transformers of various electronic devices. 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-mentioned technical problems, the application provides a high-stability ferrite core material and a preparation method thereof, and the applica...
