Soft-magnetic ferrite with low loss and high saturation flux density and preparation method therefor
The invention discloses a soft-magnetic ferrite with low loss and a high saturation flux density. The raw materials comprise materials A and materials B. The materials A comprise, by mole, 56-60 parts of iron oxide, 40-45 parts of manganese oxide, 7-10 parts of zinc oxide and 2-4 parts of copper oxide. With the total weight of the materials A as a base, the materials B comprise 2500-3000ppm, 300-700ppm of calcium oxide, 100-300ppm of niobium oxide, 400-800ppm of zirconium oxide, 1500-2000ppm of nickel oxide, 300-800ppm of bismuth oxide, 300-500ppm of molybdenum oxide, 200-500ppm of silicon oxide and 2000-2500ppm of bonding agents. The invention also discloses a preparation method for the soft-magnetic ferrite with low loss and a high saturation flux density.
