PURPOSE:To produce ferrite ceramic composite particles having improved magnetic characteristics, by coating the surface of ceramic fine particles with ferrite. CONSTITUTION:An aqueous solution of ferric chloride is put in a magnetic field, brought into contact with a great number of iron pieces to give an aqueous solution of complex, the aqueous solution of complex is blended with an aqueous solution of ferric chloride mixed with a great number of ceramic fine particles and stirred to give a conjugated aqueous solution. The conjugated aqueous solution is mixed with an aqueous solution of caustic soda, stirred, so the surface of ceramic fine particles having the surface coated with ferrite are washed with water and dried to produce ferrite ceramic composite particles. |
