NbNO is a ceramic compound combining niobium, nitrogen, and oxygen, belonging to the family of refractory transition metal oxynitrides. This material is of primary interest in high-temperature and wear-resistant applications where conventional ceramics or metals fall short, though it remains largely in research and development rather than widespread production use. Its potential lies in extreme-environment engineering—such as cutting tools, thermal barriers, and coatings—where the combination of chemical stability and mechanical properties offers advantages over monolithic nitrides or oxides alone.
