Method for producing granulated powder of r-fe-b type alloy and method for producing r-fe b type alloy sintered compact

摘要

The method for producing a granulated powder of the present invention includes the steps of: preparing an R-Fe-B alloy powder; and granulating the alloy powder using at least one kind of granulating agent selected from normal paraffins, isoparaffins and depolymerized oligomers, to prepare a granulated powder. The produced R-Fe-B alloy granulated powder is excellent in flowability and compactibility as well as in binder removability.
