METHOD FOR RECYCLING PERMANENT MAGNETS BY MELTING AND QUICKLY SOLIDIFYING

The invention relates to a recycling method for producing powders containing magnetic alloys, having the following steps : a) providing a magnetic alloy from scrap magnetic material comprising a1) at least one rare-earth metal, a2) at least one transition metal, and a3) boron; b) mixing and melting the alloys provided in steps a) and b); c) quickly solidifying the molten metal from step b) under an inert gas atmosphere, thereby forming platelets, and d) grinding the platelets obtained in step d) into a powder, wherein prior to or during step b), a magnetic alloy of a primary magnetic material comprising the components a1) to a3) is added and melted together with the alloy provided in step a), or after step d), a magnetic alloy of the primary magnetic material comprising the components a1) to a3) is added and the content of the alloy of the primary magnetic material equals 5 to 95 wt.%, based on the weight of the alloy provided in step a). The invention additionally relates to a powder which can be produced using the method according to the invention and to the applications thereof.
