· AsTaON2

AsTaON2 is an experimental ternary ceramic compound combining arsenic, tantalum, oxygen, and nitrogen—a member of the oxynitride family of wide-bandgap semiconductors. This material is primarily of research interest for next-generation wide-bandgap and ultra-wide-bandgap electronic and photonic applications, where its mixed anion chemistry offers potential for tunable electronic properties and enhanced thermal stability compared to binary nitrides or oxides alone.

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.
