CuNbON2
ceramic· 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.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
