Antimony triOxide, (Sb2O3) is a white, crystalline powder commonly used as a flame retardant in various materials, including plastics, textiles, and coatings. It acts as a synergist with halogenated flame retardants, enhancing their effectiveness in preventing the spread of fire. In addition to its flame-retardant properties, antimony triOxide, is used as a catalyst in the production of polyethylene terephthalate (PET) and as an opacifying agent in glass and ceramics, providing a milky or opaque appearance. Its versatility and effectiveness make antimony triOxide, a crucial additive in industries requiring enhanced fire safety and material durability
