NOVELTY - Manufacturing ferrite sintered magnet comprises preparing mixture including 0.1-0.5 wt.% raw material compound and crystalline carbon compound, plasticizing the mixture to produce a plasticizer, pulverizing the plasticizer to obtain a magnetic powder, obtaining a molded body by molding the magnetic powder under a magnetic field, sintering to obtain sintered body, where the crystalline carbon compound is graphene and carbon nanotubes. USE - The ferrite sintered magnet is useful in TV and communication transformers, and automobile electric devices. ADVANTAGE - The ferrite: sintered magnet exhibits isotropic properties; has high residual magnetic flux density, excellent coercivity and improved performance index. The method improves productivity.
