· JVASP-78526· Si2O

Si2O is a binary silicon-oxygen ceramic compound with a stoichiometric composition that places it between silicon monoxide (SiO) and silicon dioxide (SiO2) in the Si-O phase system. This material is primarily of research and materials science interest rather than established in high-volume industrial production, with potential applications in semiconductor processing, thin-film coatings, and specialized refractory applications where its intermediate oxidation state may offer unique thermal or electrical properties compared to conventional silica or silicates.

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.
