MANUFACTURE OF COMPOSITE MAGNETIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method by which a composite magnetic material having an excellent magnetic characteristic and a high mechanical strength can be manufactured. SOLUTION: In a method for manufacturing a composite magnetic material composed of substantially flat soft magnetic powder and an organic binder which binds the soft magnetic power to each other, the soft magnetic power is flattened by mechanically grinding magnetic slurry prepared by mixing the soft magnetic powder and organic binder granulated while water is atomized as starting magnetic powder with an organic solvent.
