· CoTaON2

CoTaON2 is a ceramic compound combining cobalt, tantalum, oxygen, and nitrogen—a mixed-valent transition metal oxynitride. This is primarily a research material under investigation for high-temperature structural applications and functional ceramic coatings, as the combination of refractory metals (tantalum) with nitrogen doping can improve hardness, oxidation resistance, and thermal stability compared to conventional oxides.

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.
