· NbWN3

NbWN₃ is a refractory metal nitride compound combining niobium and tungsten, representing the interstitial nitride family studied for high-temperature and wear-resistant applications. This material is primarily of research and development interest rather than established production use, with potential applications in hard coatings, cutting tools, and extreme-environment components where conventional alloys degrade. The niobium-tungsten nitride system is explored for its hardness, thermal stability, and resistance to oxidation at elevated temperatures, making it a candidate for next-generation tooling and high-performance surface treatments.
