ANTIMONY TRIOXIDE FOR ACES / COMPOSITES

Antimony Trioxide Antimony trioxide, also known as antimony oxide or Sb2O3, is the most widely produced com-pound of elemental anti-mony. The nations that produce the most antimo-ny trioxide are China, South Africa, Bolivia, Russia, Tajikistan, and Kyrgyzstan. Typical applications for antimony trioxide include flame retardant synergist for

Antimony | Minerals Education Coalition

Antimony is also used for pigments in plastics, paints, rubber, and for a wide variety of minor uses, including medicines, fireworks and others. Antimony oxide is a brilliant yellow color, accounting for much of the pigment use. A tiny amount of highly purified antimony metal is used in the computer industry to make semiconductors.

Antimony trioxide - Wikipedia

Antimony(III) oxide has suspected carcinogenic potential for humans. Its TLV is 0.5 mg/m 3, as for most antimony compounds. No other human health hazards were identified for antimony(III) oxide, and no risks to human health and the environment were identified from the production and use of antimony trioxide in daily life.

process antimony ore

New method developed for producing some metals | MIT News

 · The material they were using, antimony sulfide, is a molten semiconductor, which normally would not allow for the kind of electrolytic process that is used to produce aluminum and some other metals through the application of an electric current. “Antimony sulfide is a very good conductor of electrons,” Sadoway says.

Antimony Statistics and Information

The natural sulfide of antimony was known and used in Biblical times as medicine and as a cosmetic. Antimony in its elemental form is a silvery white, brittle crystalline solid that exhibits poor electrical and heat conductivity properties. Commercial forms of antimony are generally ingots, broken pieces, granules, and cast cake.
