· Si2O3

Si₂O₃ is a silicon oxide compound that exists primarily in research contexts rather than as an established commercial material; it represents an intermediate oxidation state between silicon metal and fully oxidized silica (SiO₂). While not widely deployed industrially, this composition is of interest in materials research for potential applications in semiconductors, thin films, and optical coatings, where non-stoichiometric or reduced silica phases may offer unique electronic or optical properties compared to conventional SiO₂.

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.
