· NbN

Niobium nitride (NbN) is a ceramic compound and refractory metal nitride that combines the metallic character of niobium with the hardness and thermal stability of a nitride phase. It is primarily used in thin-film applications, superconducting devices, and hard coatings where extreme hardness, chemical resistance, and thermal stability are required at elevated temperatures. NbN is notable in superconductor research as a material with critical superconducting properties, and in industrial coatings for cutting tools and wear-resistant surfaces where it outperforms softer metallic alternatives; it is also increasingly explored for barrier layers in microelectronics and as a coating material in high-performance machining applications.
