· CoTaO2N

CoTaO₂N is an experimental oxynitride ceramic compound combining cobalt, tantalum, oxygen, and nitrogen phases. This material belongs to the family of transition metal oxynitrides, which are of significant research interest for their tunable electronic and photocatalytic properties that fall between conventional oxides and nitrides. While not yet in widespread commercial production, CoTaO₂N and related compounds are being investigated for energy conversion and environmental remediation applications where the mixed anion structure enables enhanced performance compared to single-anion ceramics.

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.
