Structure
Synonyms	Antimony white, Antimony Trioxide
Molecular Formula	Sb2O3
Solubility	Insoluble in water. it is soluble in concentrated hydrochloricand sulfuric acids.and strong alkalies.
Appearance	white, odorless crystallinepowder.
Application	FlameRetardant Synergist -Antimony Trioxide in combination with a halogen source constitutes anextremely effective flame retardant for use in a broad range of polymers. Chlorine or brmine are the halogens most often emplayed,and may be present in the polymer chain.Such is the case withpolyvinyl chloride or brominated resins. Dtherwise a halogen-containing compound is simply added to the system. Antimony Trioxide has minimal effect on the physical and chemical properties of most polymers.For this reason, and fur itssuperior flame retardant synergism.Antimny Trinxide is the inorganic additive of choice for most applications.
