Low-loss soft magnetic ferrite material and preparation method thereof
The invention discloses a low-loss soft magnetic ferrite material which comprises main materials and auxiliary materials, wherein the main materials comprise the following components in parts by mole: 57 to 60 parts of ferric nitrate, 40 to 42 parts of manganese nitrate, 9-12 parts of zinc nitrate and 8 to 10 parts of nickel nitrate; by using the total weight of the main materials as a reference, the auxiliary materials comprise the following components: 300 to 400 ppm of neodymium oxide, 300 to 400 ppm of vanadium oxide, 400 to 600 ppm of niobium oxide, 300 to 700 ppm of boron oxide, 50 to 200 ppm of calcium carbonate, 20 to 100 ppm of lithium carbonate, 20 to 80 ppm of barium carbonate, 250 to 800 ppm of silica, 2000 to 2500 ppm of an adhesive, 3*10<6> to 5*10<6> ppm of an adsorbent, 300 to 500 ppm of an emulsifier. The invention also discloses a method for preparing the low-loss soft magnetic ferrite material; the magnetic core is low in loss and the saturation induction density is high.
