Antimony Trioxide Micron Powder

Antimony trioxide, also known as antimony oxide or Sb2O3, is the most widely produced compound of elemental antimony. Antimony trioxide is formed by reacting antimony trichloride (SbCl₃) with water. It is used in combination with some brominated flame retardants and might also be used in conjunction with zinc borate. The bulk antimony trioxide has been reported to have high electrical resistivity as well as energy band gap. Typical applications for antimony trioxide include flame retardant synergist for use in plastics, rubber, paints, paper, textiles, and electronics; polyethylene terephthalate polymerization catalyst; a clarifying agent for glass; an opacifier for porcelain and enamel; and a white pigment for paint. When used as a flame retardant, antimony trioxide is often used in combination with halogenated compounds. Antimony trioxide is used as a synergist to enhance the activity of the halogenated flame retardant. Other applications of antimony trioxide include a clarifying agent for glass, an opacifier for porcelain and enamel, and a white pigment.
