What is a Antimony oxide (Sb₂O₃)?

Antimony oxide (Sb₂O₃) is an inorganic compound composed of antimony and oxygen, typically found as a white crystalline or powdery substance. Antimony, a metal, forms various compounds in its oxidized state, with Sb₂O₃ being one of the most widely used. It is chemically stable and thermally resistant. Industrially, Sb₂O₃ is commonly used as a flame retardant, enhancing the fire resistance of materials like polyester, nylon, plastics, and rubber. This reduces the risk of fire and improves safety in various products.

Sb₂O₃ is also utilized in the glass industry, improving the refractive index of transparent and lead glass. Additionally, it is used in electronics and semiconductors for conductive and insulating purposes. Moreover, Sb₂O₃ serves as a pigment and a catalyst in chemical reactions. When handling, it is important to wear protective equipment to avoid inhalation or skin contact, as it can be toxic if ingested in large amounts.
