· CaTaON2

CaTaON2 is an experimental ceramic compound combining calcium, tantalum, oxygen, and nitrogen—a member of the oxynitride ceramic family designed to achieve properties intermediate between traditional oxides and nitrides. This material is primarily of research interest for photocatalysis and optoelectronic applications, where its tunable band gap and mixed-anion chemistry offer potential advantages over conventional single-anion ceramics; it represents an active area of materials development rather than an established engineering material with widespread industrial deployment.

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.
