· SiOsO2N

Silicon oxynitride (SiON) is an advanced ceramic compound combining silicon, oxygen, and nitrogen phases, engineered to provide enhanced thermal stability and oxidation resistance compared to pure silica or silicon nitride alone. This material is primarily used in high-temperature structural applications, protective coatings, and aerospace/automotive engine components where thermal cycling resistance and chemical durability are critical. Its mixed oxide-nitride composition makes it notable for bridging the properties of silicates and nitride ceramics, offering improved performance in aggressive thermal and oxidative environments while maintaining reasonable processing flexibility.

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.
