Antimony Trioxide Properties
The value of Sb2O3 in industry comes from its role as a flame retardant synergist. It is insoluble in water, soluble in acids, has a molecular weight of 291.5 g/mol and a melting point of 656°C. Paired with halogenated systems it improves fire resistance while keeping mechanical and aesthetic properties intact, which is why it is widely specified across plastics, textiles and electronics.
