· KTaO2N

KTaO₂N is an oxynitride ceramic compound combining potassium, tantalum, oxygen, and nitrogen in a perovskite-related structure. This material is primarily investigated in academic and early-stage industrial research contexts for visible-light photocatalytic applications, where it shows promise for water splitting and pollutant degradation due to its reduced bandgap compared to oxide-only alternatives. Its nitrogen incorporation distinguishes it from traditional tantalate ceramics and positions it as a candidate for next-generation photocatalytic and energy conversion systems, though commercial deployment remains limited.

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.
