Al-Ce alloys designated by Aluminum Association CMI developed alloys that have passed key commercial milestone, and have been accorded official designations by The Aluminum Association, opening the door to global industrial applications
Ce-based gap magnets match high-temperature performance of neo CMI research at Ames Laboratory Achievement showed that at certain temperatures a cerium-based magnet matches the energy product of and exceeds the coercivity of neodymium permanent magnets
High-performance critical-element-free permanent magnets CMI research at Ames Laboratory demonstrated that mechanochemical preprocessing is beneficial for nitrogen insertion/topotactic extraction
Lower-cost commercial grade Ce enhances performance and reduces cost in gap magnets CMI research with lower-cost commercial grade cerium enhances performance and reduces cost in gap magnets. Also, the less costly “dirty” cerium samples showed as much as a 5% increase of both coercivity and magnetization, resulting in better energy product.
CMI research on cover of journal: Sustainable urban mining of critical elements from magnet and electronic wastes Journal publication on the acid-free leaching process for recycling rare-earth elements and cobalt from waste magnet and e-waste materials is published and highlighted as a supplementary cover in ACS high impact journal
Optimized shredding conditions enables improvement in leaching time for REEs in end-of-life hard disk drives (HDDs) A HDD shredder designed to result in optimally shredded feedstock for acid-free dissolution and also minimize the amount of magnets attached to the cutters during shredding has been commissioned. Consequently, only ~60% of the original leaching time is required and a dissolution efficiency of ≥72% wt.% was obtained for HDDs.
