摘要： The present invention relates to ferrite particles for bonded magnets and a resin composition for bonded magnets which can provide a bonded magnet molded product capable of realizing a high magnetic force and a complicated multipolar waveform owing to such a feature that the ferrite particles are readily and highly oriented against an external magnetic field in a flowing resin upon injection molding, as well as a bonded magnet molded product obtained by injection-molding the above composition. According to the present invention, there are provided ferrite particles for bonded magnets which have a crystallite size of not less than 500 nm as measured in an oriented state by XRD, and an average particle diameter of not less than 1.30 µm as measured by Fisher method; a resin composition for bonded magnets; and a molded product obtained by injection-molding the composition.

摘要： The object of the present invention relates to ferrite particles for bonded magnets and a resin composition for bonded magnets which is capable of obtaining a bonded magnet molded product having a good magnetic force and a magnetic waveform as well as high iHc and Hk by injection molding. The present invention aims at providing a bonded magnet molded product using the ferrite particles and the resin composition. The aforementioned object of the present invention can be achieved by ferrite particles for bonded magnets which have a crystal distortion of not more than 0.14 as measured by XRD, and an average particle diameter of not less than 1.30 µ m as measured by Fisher method; a resin composition for bonded magnets; and a molded product obtained by injection-molding the resin composition.
