Beschreibung
Zusammenfassung:	Disclosed is an R-Fe-B porous magnet having an aggregate structure of Nd2Fe14B crystal phases having an average crystal grain size of not less than 0.1 µm but not more than 1 µm. At least a part of the R-Fe-B porous magnet has a porous structure comprising fine pores having a length of not less than 1 µm but not more than 20 µm. La présente invention concerne un aimant poreux R-Fe-B possédant une structure agrégée de phases cristallines Nd2Fe14B dont la taille moyenne du grain de cristal ne descend pas en dessous de 0,1 µm et ne dépasse pas 1 µm. Une partie au moins de l'aimant poreux R-Fe-B possède une structure poreuse dotée de fins pores dont la longueur ne descend pas en dessous de 1 µm et ne dépasse pas 20 µm.
