· YSiON2

YSiON2 is an yttrium silicon oxynitride ceramic compound that combines the thermal stability and oxidation resistance of oxide ceramics with the mechanical strength of nitride ceramics. This material is primarily investigated for high-temperature structural applications where both thermal shock resistance and chemical durability are critical, such as in aerospace propulsion systems and advanced heat-exchange environments. YSiON2 represents a promising research-stage composition in the oxynitride family, offering potential advantages over monolithic oxides or nitrides by balancing toughness, creep resistance, and environmental stability 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.
