Antimony (III) oxide is an opacifying agent for glasses, ceramics and enamels. Some specialty pigments contain antimony. Antimony (III) oxide is a useful catalyst in the production of polyethylene terephthalate (PET plastic) and the vulcanization of rubber.
Antimony trioxide can be produced by roasting antimony trisulfide; by burning antimony in air or oxygen; by alkaline hydrolysis of antimony halides (trichloride, tribromide, or triiodide); or by hydrolysis of antimony trisulfide with superheated steam.
THIS chapter reviews the physical and chemical properties, toxicokinetics, toxicological, epidemiological, and exposure data on antimony trioxide. The subcommittee used that information to characterize the health risk from exposure to antimony trioxide.
Antimony trioxide is a white solid. It is the most common antimony compound. It does not dissolve in water. It reacts with oxidizing agents to make antimony pentoxide and with reducing agents to make antimony or stibine. It reacts with concentrated acids to make antimony (III) salts and dissolves in strong bases .
Jun 6, 2023 · Antimony trioxide is an inorganic compound widely used in various industries due to its unique properties and versatile applications. This article provides an overview of antimony trioxide, including its chemical properties, common uses, and safety considerations.
