· JVASP-1363· TmN

Thulium nitride (TmN) is a refractory ceramic compound belonging to the rare-earth nitride family, characterized by high hardness and thermal stability. While primarily a research and development material rather than a commodity engineering ceramic, TmN is investigated for high-temperature structural applications and as a functional material in optoelectronics and solid-state physics where rare-earth properties are exploited. Interest in this compound stems from its potential in extreme environment applications and its unique electronic/optical characteristics compared to more common nitride ceramics.
