Wide-temperature-range low-power-consumption soft-magnetic ferrite material and preparation method therefor
The invention discloses a preparation method for a wide-temperature-range low-power-consumption soft-magnetic ferrite material. The preparation method comprises steps: ferric chloride, manganese chloride, cupric chloride and zinc chloride are employed as main materials, after the main materials are added in deionized water, mixed and dissolved completely, polyvinyl alcohol is added, and a first material is obtained; sodium bicarbonate, ammoniacal liquor and triethanolamine are mixed uniformly and a second material is obtained; the first material is added in the second material dropwise, stirring is carried out continuously during the dripping process, after stirring is carried out for 3-4h, the mixture is allowed to stand, filtering is carried out, and a third material is obtained; the third material is dried, pre-burnt and cooled and a powder material is obtained; neodymium oxide, lanthanum oxide, yttrium oxide, vanadium oxide, titanium oxide, zirconium oxide, indium oxide, lithium carbonate, silicon dioxide and carbon fibers are added in the powder material, the mixture is mixed uniformly, the mixture is added in a high pressure reaction vessel, a hydro-thermal reaction is carried out, and a wide-temperature-range low-power-consumption soft-magnetic ferrite material is obtained. The invention also discloses a wide-temperature-range low-power-consumption soft-magnetic ferrite material. The scope of the usage temperature is widened, and magnetic core loss is lowered.
