NdCo4B
metal· JVASP-57732· NdCo4B
NdCo4B is an intermetallic compound combining neodymium, cobalt, and boron, belonging to the rare-earth transition metal boride family. This material is primarily of research and specialized industrial interest for permanent magnet applications, leveraging neodymium's strong magnetic properties in conjunction with cobalt's high Curie temperature and boron's role in stabilizing the crystal structure. It represents an alternative formulation within the broader class of rare-earth magnets, explored for applications requiring high magnetic performance at elevated temperatures or improved thermal stability compared to conventional NdFeB magnets.
