NiNbO2N

NiNbO2N is a ceramic compound in the metal oxynitride family, combining nickel, niobium, oxygen, and nitrogen into a hard ceramic phase. This material is primarily of research and development interest for applications requiring high hardness and thermal stability; it belongs to the broader class of transition metal oxynitrides being explored as coatings and structural ceramics where conventional oxides or nitrides fall short. Industrial adoption remains limited, but the material is notable for potential use in extreme environments where wear resistance, chemical inertness, and thermal durability are critical.
