· CaTaNO2

CaTaNO2 is an experimental oxynitride semiconductor compound combining calcium, tantalum, nitrogen, and oxygen elements, representing a hybrid class of materials that bridges ceramic and semiconductor properties. This material family is primarily of research interest for photocatalytic and optoelectronic applications, where the mixed anion (N and O) composition can be engineered to tune electronic bandgaps and light absorption—potentially offering advantages over single-anion alternatives like Ta2O5 or Ta3N5. CaTaNO2 remains largely in development stages, with potential value in visible-light photocatalysis, solar energy conversion, and environmental remediation where bandgap engineering through mixed anion incorporation is desirable.

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.
