· YSiO2N

YSiO₂N is an advanced oxynitride ceramic material combining yttrium, silicon, oxygen, and nitrogen phases. This material belongs to the rare-earth oxynitride family, developed for high-temperature structural applications where conventional silicates degrade. It is primarily investigated for aerospace engine components, wear-resistant coatings, and high-temperature bearing applications where its thermal stability and chemical resistance offer advantages over oxide-only ceramics, though it remains largely in development and specialized use rather than mainstream production.

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.
