· JVASP-135678· As3O

As₂O₃ is an inorganic ceramic compound belonging to the arsenic oxide family, typically encountered as a brittle, crystalline solid in industrial and research contexts. This material appears primarily in specialized applications requiring arsenic compound properties, including historical use in glass manufacturing, semiconductor processing, and laboratory research; however, its toxicity and regulatory restrictions severely limit contemporary engineering applications compared to safer alternative ceramics. Engineers would encounter this material mainly in legacy systems, materials research, or highly specialized industrial processes where arsenic oxides provide unique chemical or optical properties unavailable from substitute materials.

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.
