· SiSrO2N

SiSrO₂N is an oxynitride ceramic compound combining silicon, strontium, oxygen, and nitrogen phases, representing a specialized ceramic family engineered for high-temperature structural applications. This material is primarily investigated for aerospace and thermal barrier applications where enhanced high-temperature strength and oxidation resistance are required; it belongs to an emerging class of rare-earth-free oxynitride ceramics designed as cost-effective alternatives to traditional nitride and oxide ceramics. The strontium-containing composition offers potential advantages in thermal cycling resistance and grain boundary strengthening compared to conventional SiAlON (silicon aluminum oxynitride) systems.

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.
