<P>PROBLEM TO BE SOLVED: To provide ferrite particle powder for a bonded magnet in which moldability is fine, in particular, mechanical strength is large when it is rapidly cooled upon injection cooling, and it is possible to obtain a bonded magnet molded body in which a magnetic characteristic of a molded product is excellent, a resin composition for the bonded magnet, and the bonded magnet molded body such as a magnet roll using the ferrite particle powder and the composition. <P>SOLUTION: In the ferrite particle powder for the bonded magnet adsorbing and/or containing phosphorous, a phosphorous content in a ferrite is 120 to 5,000 mg/kg (0.012 to 0.5 wt.%) as P. The resin composition for the bonded magnet formed of the ferrite particle powder for the bonded magnet and the magnet roll are obtained. <P>COPYRIGHT: (C)2008,JPO&INPIT |
