US5783166A Process for producing antimony trioxide

A process for the production of antimony trioxide comprising the steps of: (i) reacting antimony trisulfide with iron (III) chloride to produce antimony trichloride; and (ii) hydrolyzing antimony trichloride to produce antimony trioxide. In a preferred embodiment, the process is substantially closed or near-closed loop. Antimony trioxide is a known flame retardant for use in plastics, ceramics
