METHOD FOR MANUFACTURING Sm-Fe-N-BASED MAGNETIC PARTICLE POWDER, RESIN COMPOSITION FOR BONDING MAGNET CONTAINING Sm-Fe-N-BASED MAGNETIC PARTICLE POWDER, AND BONDING MAGNET

摘要

PROBLEM TO BE SOLVED: To provide Sm2Fe17N3which is high in homogeneity and can exhibit stable characteristics, and to provide a resin composition for a bonding magnet containing the Sm-Fe-N-based magnetic particle powder, and the bonding magnet.

SOLUTION: The method for manufacturing the Sm-Fe-N-based magnetic particle powder comprises producing an SmFe compound by effecting reduction-diffusion reaction using a samarium oxide-iron composite and metal calcium, then subjecting the SmFe compound to nitriding reaction. The Sm-Fe-N-based magnetic particle powder can be manufactured by laminating the samarium oxide-iron composite and the metal calcium, and installing the laminate into a vessel in the case of performing the reduction diffusion.
