Cellcom FR/ATO-10, Antimony trioxide is used mainly as a fire prevention additive and pigment (concentration:1~13%), the finer fraction is used for pigmentation .

The flame retardant property, however, is not affected by particle size. This property is based on antimony trioxide reacting in the event of a fire with the surrounding material, with the result that a protective layer of various antimony compounds covers the combustible materials. Since the formation of these compounds consumes heat and because they are generally difficult to ignite, they protect the underlying material from ignition. The presence of thermally unstable halogen compounds accelerates the protective impact of antimony. Antimony trioxide is therefore nearly always used together with high halogenated organic compounds such as chloroparaffins.

Antimony products have a wide variety of uses. In today's world their use as a flame-retardant synergist is a large and important application. Antimony trioxide do not react as flame retardants directly. They are used as synergists to enhance the activity of halogenated flame retardant by stepwise releasing the halogenated radicals to retard gas phase chain reaction of flame spread. Antimony trioxide has excellent synergic effects when it is used with Decabromodiphenyl oxide. This is especially evident in PVC, where antimony products at a small addition rate (usually less than 10%) can dramatically improve the flame retardancy of rigid and plasticized PVC articles.

In glass manufacturing, antimony trioxide is used instead of arsenic as a plaining agent. When the parasion of glass is heated, antimony trioxide is gasified, whereupon bubbles of gas are formed which serve to create a remixture of molten glass and also to trap other substances in the gas bubbles formed and to remove them from the glass.

And antimony trioxide is used as catalyst in PET production, flocculent in titanium dioxide production, paints and adhesives industries, pigments and ceramic frittes.


Antimony trioxide is suspected to cause the cancer, so careful precautions and good ventilation of handling and mixing area are required.
