NdB6 (neodymium hexaboride) is a rare-earth ceramic compound belonging to the hexaboride family, characterized by high hardness and thermal stability. It is primarily investigated for use in thermionic electron emitters, high-temperature structural applications, and specialized cutting tools where extreme wear resistance and thermal performance are required. Compared to conventional cathode materials and refractory ceramics, NdB6 offers superior electron emission efficiency at elevated temperatures, making it valuable for vacuum electronics and plasma generation devices, though adoption remains largely in research and specialized industrial sectors.
