| titleOfInvention | Manganese-zinc ferrite magnetic core with high saturation magnetic flux density and preparation method thereof |
| abstract | The invention discloses a manganese-zinc ferrite magnetic core with high saturation magnetic flux density and a preparation method thereof, belonging to the technical field of magnetic materials. The preparation method of the manganese-zinc ferrite magnetic core adopts manganese powder, zinc oxide powder, silicon dioxide, calcium oxide, vanadium pentoxide and iron powder as raw materials; firstly, manganese powder, zinc oxide powder and iron powder are subjected to synthesis reaction with hydrochloric acid and liquid ammonia in sequence, and then the manganese-zinc ferrite magnetic core can be obtained through presintering, doping and ball milling, compression molding, sintering treatment and air gap cutting treatment. According to the invention, iron powder, manganese powder, zinc oxide powder and the like are used as initial raw materials, and the iron powder, the manganese powder and the zinc oxide powder are sequentially subjected to synthetic reaction and presintering treatment with hydrochloric acid and liquid ammonia to obtain ferric oxide, manganese oxide and zinc oxide with less impurity content, so that the physicochemical reactions of the components can be uniform in subsequent sintering treatment, and the purposes of reducing the porosity of the magnetic core, improving the density of the magnetic core and improving the density of saturated magnetic flux are achieved. |
