Arsenic trisulfide manufactured into amorphous form is used as a chalcogenide glass for infrared optics. It is transparent between 620 nm and 11 Âµm. The arsenic trisulfide glass is more resistant to oxidation than crystalline arsenic trisulfide, which minimizes toxicity concerns.
Description: Arsenic's name comes from the Greek term for an arsenic compound, orpiment (arsenic trisulfide). Arsenic is a metalloid element, which, like phosphorus, has two main forms. One is a brittle, gray metallic form and the other is a yellow, non-metallic solid.Yellow arsenic is the more reactive and unstable of the pair. Arsenic is stable, being unaffected by air, water, most acids and alkalis.Arsenic has no liquid phase; the solid sublimes directly into a vapor.rsenic has semiconductor properties and is used in making transistors. It is also used in alloys, glass production, pyrotechnics and wood preservatives. An arsenic-gallium compound is used in making lasers.
