Ferrite material used for motors
The invention discloses a ferrite material used for motors. The ferrite material comprises, by weight, 140 to 160 parts of ferric oxide, 2 to 5 parts of lanthanum oxide, 1 to 4 parts of barium oxide, 0.5 to 1.5 parts of manganese oxide, 0.2 to 0.8 parts of aluminum oxide, 2 to 4 parts of zinc oxide, 1 to 4 parts of strontium carbonate, 0.2 to 0.8 part of an additive, and 0.2 to 0.8 part of a dispersant. The formula of the ferrite material is reasonable; the ferrite material is obtained via presintering, fine grinding, moulding, and sintering, material performance is excellent, and the ferrite material is suitable to be applied to motors. The additive is a mixture of a camphor alcohol solution, a boric acid solution, and diammonium hydrogen phosphate, and is capable of solving the problems of pore; and the dispersant is a mixture of molybdenum dioxide, magnesium stearate, and polyethylene glycol, and is capable of reducing grain size.
