Abstract

PURPOSE: To dispense with baking process and improve economy and productivity by using adhesives for solidifying powder of magnetic substance.
CONSTITUTION: Substance 1 in gel or sol condition of proper hardness is prepared by mixing powder of magnetic substance such as Ba ferrite or Sr ferrite with solution of adhesives at room temperature, for example at the mixture rate in weight, i.e. 100:20W30 (adhesive + solvent) in powder weight. Substance 1 thus obtained is poured into the die or the concave portion 2a of semi-finished product 2 and solidified naturally. Magnetic field is applied to this solidified magnetic substance to form magnet.
