Method and apparatus for producing granulated powder of rare earth alloy and method for producing rare earth alloy sintered compact

摘要

A method of making a rare-earth alloy granulated powder according to the present invention includes the steps of: preparing a rare-earth alloy powder; generating remanent magnetization in the powder; and granulating the powder by utilizing agglomeration force produced by the remanent magnetization of the powder. Since the agglomeration force produced by the remanent magnetization is utilized, the addition of a granulating agent may be omitted.
