· SiScON2

SiScON2 is a ternary ceramic compound combining silicon, scandium, and oxygen in a nitride-based system, representing an advanced high-temperature ceramic material within the oxynitride family. This material is primarily of research and developmental interest for ultra-high-temperature structural applications where thermal stability, oxidation resistance, and mechanical performance at elevated temperatures are critical requirements. The scandium addition to silicon oxynitride systems is notable for potentially improving fracture toughness and thermal shock resistance compared to conventional silicon nitride ceramics, making it relevant for aerospace, power generation, and extreme environment applications.

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.
