· JVASP-138128· AsO

Arsenic oxide (AsO) is a ceramic compound belonging to the metal oxide family, though this specific stoichiometry is uncommon and may represent a research-phase or non-stoichiometric composition. Arsenic oxides are primarily of interest in specialized applications such as optoelectronic devices, glass additives for infrared transmission, and historical use in semiconductors, though toxicity concerns and regulatory restrictions severely limit commercial deployment in most regions. Engineers would encounter arsenic oxide mainly in legacy systems, research contexts exploring wide-bandgap semiconductors, or niche high-temperature optical applications where its thermal stability and refractive properties justify careful handling protocols.

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.
