Antimony(III) oxide (Sb2O3), often known as antimony trioxide or antimony oxide, is a white solid often considered the most important compound of antimony. The compound is acquired through oxidization of raw minerals containing it and purified by sublimation, or alternatively through the treatment of metallic antimony in furnaces.

Applications

Antimony oxide stands out as one of the most versatile and widely used compounds of antimony, with commercial applications in a large number of industries. Antimony oxide’s primary application is to generate flame-retardant properties in polymers through combination with halides.

These flame-retardant polymers are in turn used in countless industries, including electronics, clothing, specialty coatings, and more.

Outside of this primary application, antimony oxide sees these uses:

  • Opacifier. Used in glasses, ceramics, and enamels to increase refractive index. 
  • Pigments. The same refractive and optical properties which make antimony oxide of value as an opacifier make it of interest in certain specialty pigments.
  • Catalysis. Sb2O3 is also used as a catalyst for vulcanization of rubber and the production of certain plastics.

AHP Materials can provide Sb2O3 at purities of 99.999% or 99.9999% as part of our standard catalog of products. If you would like to learn more about custom antimony oxide orders, or have questions about orders, pricing, or shipping, contact us today.
