Permanent magnetic ferrite for automobile motor and manufacturing method of permanent magnetic ferrite
The invention discloses a permanent magnetic ferrite for an automobile motor and a manufacturing method of the permanent magnetic ferrite. The permanent magnetic ferrite for the automobile motor comprises the following raw materials in parts by weight: fine iron powder, barium carbonate, strontium carbonate, silicon dioxide, polyvinyl alcohol, aluminum oxide, cobalt oxide, lanthanum oxide, calcium gluconate and boric acid. When the permanent magnetic ferrite is manufactured, the fine iron powder prepared by using an iron sand resource is used as a preparation raw material, so that the production cost is reduced; and the powder is firstly subjected to coarse grinding and fine grinding treatment, so that the prepared powder is uniform in particle size distribution and low in crystal grain damage degree. The manufacturing method is simple in process and convenient to operate; and the manufactured permanent magnetic ferrite is rich in raw material source, low in cost, good in product cost performance, favorable in magnetic property, relatively high in residual magnetic flux density, relatively good in intrinsic coercivity and high in operability and practicability.
