CuNbON2

CuNbON2 is a ternary ceramic compound combining copper, niobium, oxygen, and nitrogen phases—a research material in the oxycarbide/oxynitride family that bridges metallic and ceramic characteristics. This material system is primarily explored in academic and advanced materials research contexts for hard coatings and wear-resistant applications, where the copper component can enhance thermal conductivity and the refractory niobium oxide provides hardness. Its combination of properties makes it a candidate alternative to traditional hard ceramics (like TiN or CrN) in specialized applications requiring both wear resistance and improved fracture toughness.
