  • Patent number: 10717131
    Abstract: The present invention discloses a method of manufacturing, powder making device for rare earth magnet alloy powder, and a rare earth magnet. The method comprises a process of fine grinding at least one kind of rare earth magnet alloy or at least one kind of rare earth magnet alloy coarse powder in inert jet stream with an oxygen content below 1000 ppm to obtain powder that has a grain size smaller than 50 ?m. Low oxygen content ultra-fine powder having a grain size smaller than 1 ?m is not separated from the pulverizer, and the oxygen content of the atmosphere is reduced to below 1000 ppm in the pulverizer when crushing the powder. Therefore, abnormal grain growth (AGG) rarely happens in the sintering process. A low oxygen content sintered magnet is obtained and the advantages of a simplified process and reduced manufacturing cost are realized.
