· CoSiON2

CoSiON₂ is an experimental ceramic compound combining cobalt, silicon, oxygen, and nitrogen—a member of the oxynitride ceramic family designed to achieve enhanced hardness, thermal stability, and wear resistance beyond conventional oxides. While primarily a research material rather than established in mainstream production, oxynitride ceramics like this are being developed for high-performance cutting tools, wear-resistant coatings, and thermal barrier applications where the dual bonding character of oxynitride phases offers advantages over purely oxide or nitride 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.
