Progress in Recycling of Sintered NdFeB Magnet Wastes Significant efforts have been put into the recycling of bulk sintered NdFeB magnet wastes around the world in the past decade because bulk Nd–Fe–B sintered magnet wastes are valuable secondary rare-earth resources. There are two major facts behind the efforts. First, the waste magnets contain total rare-earth [...]
HSMAG Exhibited The Battery Show in North America The Battery, Electric Vehicle Technology and Power Reserve Exhibition 2018 was held in Detroit, USA. HSMAG exhibited main products of rare earth permanent magnets (NdFeB and SmCo permanent magnets used in new energy vehicle drive motors). We won good attention and praise of visitors, and achieved complete [...]
Sintered NdFeB Magnets as Anisotropic Bonded Magnets via Hydrogen Decrepitation Process Abstract The scrap sintered Nd–Fe–B magnets were recycled as the raw materials for bonded magnets using the hydrogen decrepitation (HD) process. The HD powders have the lowest oxygen and hydrogen content by hydro-genation at 150°C with 1 bar H2 pressure and dehydro-genation at 600°C. [...]
