· JVASP-7986· TbN

TbN is a ceramic compound composed of terbium nitride, belonging to the family of rare-earth nitride ceramics. This material combines the hardness and refractory properties characteristic of nitride ceramics with the unique electronic and magnetic properties of terbium, making it of particular interest in advanced functional applications. While primarily explored in research and development rather than high-volume production, TbN is notable for potential use in specialized environments requiring thermal stability, hardness, and materials with engineered electronic or magnetic properties—areas where conventional ceramics or transition-metal nitrides may be limited.
