High-impedance low-power-consumption soft magnetic ferrite material and preparation method thereof
The invention discloses a preparation method of a high-impedance low-power-consumption soft magnetic ferrite material. The preparation method comprises the following steps: weighing ferric nitrate, nickel nitrate, cupric nitrate and zinc nitrate as main ingredients, adding the main ingredients into deionized water, stirring and dissolving completely, and then adding polyethylene glycol to obtain a material A; evenly mixing sodium hydroxide, ammonia water and 1,3-propane diamine, to obtain a material B; dropwise adding the material B to the material A, stirring constantly in the dropwise adding process, then stirring for 3-4 h, allowing to stand for 9-10 h, and filtering to obtain a material C; drying the material C, presintering, heating up to 900-920 DEG C, and cooling to obtain a pre-sintered material; and adding molybdenum oxide, cobalt oxide, rhenium oxide, titanium oxide, zirconium oxide, indium oxide, manganese oxide, boron oxide, silicon dioxide and carbon fiber into the pre-sintered material, mixing evenly, adding into a high pressure reactor, carrying out a hydrothermal reaction, and taking out to obtain the high-impedance low-power-consumption soft magnetic ferrite material.
