FERROMAGNETIC PARTICLE POWDER, METHOD FOR PRODUCING SAME, ANISOTROPIC MAGNET AND BONDED MAGNET |
摘要 |
The present invention relates to Fe 16 N 2 particles in the form of a single phase which are obtained by subjecting iron oxide or iron oxyhydroxide whose surface may be coated with at least alumina or silica, if required, as a starting material, to reducing treatment and nitridation treatment, a process for producing the Fe 16 N 2 particles in the form of a single phase for a heat treatment time of not more than 36 hr, and further relates to an anisotropic magnet or a bonded magnet which is obtained by magnetically orienting the Fe 16 N 2 particles in the form of a single phase. The Fe 16 N 2 particles according to the present invention can be produced in an industrial scale and have a large BH max value. |
