· TaYO2N

TaYO₂N is a tantalum-based oxynitride ceramic combining tantalum, yttrium, oxygen, and nitrogen phases. This is a research-stage material belonging to the high-entropy or multi-phase ceramic family, developed to achieve enhanced hardness, thermal stability, and oxidation resistance for extreme-environment applications. While not yet widely deployed in production, oxynitride ceramics like TaYO₂N are investigated for applications requiring refractory properties and resistance to thermal shock and chemical attack at elevated temperatures.

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.
