Antimony(III) Oxide (Sb₂O₃) / Antimony(V) Oxide (Sb₂O₅)

Antimony(III) Oxide (Sb₂O₃) (Antimony trioxide) is a white solid and is the most important commercial compound of antimony.

Antimony(V) Oxide (Sb₂O₅) (Antimony pentoxide) is a yellow powdery solid that is very slightly soluble in water.
Typical Applications

Antimony(III) Oxide (Sb₂O₃) is used as a flame retardant for textile materials and as a source to prepare other antimony compounds. It is also used as a catalyst in the production of polyethylene terephthalate (PET plastic) and in the vulcanization of rubber. It is an opacifying agent for glasses, ceramics, and enamels.

Antimony(V) Oxide (Sb₂O₅) is used as a flame retardant for acrylonitrile-butadiene-styrene (ABS) polymer, plastics, rubbers, paper, and textiles. It is a source to prepare other antimony compounds and is employed as a catalyst in certain polymerization and oxidation reactions.

Packaging Options

Jars, pails, drums, multi-ply paper bags, bulk bags, and fiberboard containers

Sustainable Qualities

Antimony (III) Oxide and Antimony (V) Oxide are considered sustainable materials because they can be recycled and reused multiple times without losing their properties or quality. These Oxides are commonly used as flame retardants and as additives in plastics and other materials. They are also used in the manufacturing of batteries, ceramics, and glass. By using these Oxides, manufacturers can reduce their reliance on virgin materials and contribute to a more circular economy by extending the lifespan of existing resources. Additionally, recycling Antimony Oxides can help reduce the amount of waste generated and reduce the environmental impact of production processes.
