Applications

Antimony(III) oxide finds use as flame retardant wherein it synergistically acts with halogenated materials. It is employed in opacifying glasses, ceramics and enamels. In the preparation of optical and ruby glass, antimony trioxide serves as a bubble remover. Further, it is a useful catalyst in the production of polyethylene terephthalate (PET plastic) and the vulcanization of rubber.

Notes

It is stable under normal conditions. Incompatible with acids, bases and reducing agents.
