High-magnetoconductivity wide-temperature low-loss soft magnetic ferrite and preparation method thereof
The invention discloses a preparation method of a high-magnetoconductivity wide-temperature low-loss soft magnetic ferrite. The preparation method comprises the steps: weighing ferric nitrate, nickel nitrate and zinc nitrate as main ingredients, adding into deionized water, stirring and dissolving completely to obtain a material A; adding N-methyl diethanolamine, monoethanolamine and diglycolamine into deionized water, evenly mixing, then adding 1,2-propylene glycol, sorbitol, xylitol and polyethylene glycol to obtain a material B; dropwise adding the material B to the material A, stirring constantly in the dropwise adding process, then stirring for 1-2 h, next aging for 7-9 h, centrifuging, drying, then roasting, and cooling to obtain a powder material; adding zirconium oxide, titanium oxide, vanadium oxide, magnesium oxide, bismuth oxide, alumina, boron oxide, tungsten carbide and polysulfone resin into the powder material, carrying out spray granulation, carrying out tabletting molding, and sintering to obtain the high-magnetoconductivity wide-temperature low-loss soft magnetic ferrite. The invention also discloses the high-magnetoconductivity wide-temperature low-loss soft magnetic ferrite.
