<P>PROBLEM TO BE SOLVED: To provide a ferrite particle powder for bond magnet and a resin composition for bond magnet which are excellent in compacting properties, especially, in mechanical strength even when quenched during injection cooling bond magnet compact, and can impart superior magnetic characteristics to a compact article, and to provide a bond magnet compact such as a magnet roll using the ferrite particle powder and the resin composition. <P>SOLUTION: The ferrite particle powder for the bond magnet formed by adsorbing and/or incorporating a phosphoric acid compound which does not cause decomposition and/or in-molecule dehydration at 200 to 400°C is characterized in that ferrite contains phosphorus in an amount P of 120 to 5,000 mg/kg (0.012 to 0.5 wt.%). Further, there are provided the resin composition for the bond magnet and the magnet roll. <P>COPYRIGHT: (C)2010,JPO&INPIT |
