· SiYOFN

SiYOFN is an oxynitride ceramic compound containing silicon, yttrium, oxygen, and nitrogen elements, belonging to the family of advanced ceramics engineered for high-temperature structural applications. This material is primarily used in aerospace and automotive industries for components requiring exceptional thermal stability, creep resistance, and mechanical strength at elevated temperatures, such as turbine engine parts and exhaust systems. SiYOFN represents research into non-oxide ceramics that can outperform traditional silicon nitrides and aluminas in demanding thermal environments where oxidation resistance and phase stability are critical.

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.
