Antimony Oxides

Antimony Oxides

 

the compounds of antimony with oxygen, namely, Sb2O3, Sb2O4, and Sb2O5. Antimony trioxide occurs as colorless, readily sublimable crystals; it is obtained by the distillation roasting of antimony ores and is used in the textile industry and in the production of paints. The pentoxide Sb2O5 occurs as light yellow crystals; this oxide is obtained by the calcination of xSb2O5·yH2O and is used in the pharmaceutical industry and in the production of glass, ceramics, paints, varnishes, and textiles.

In principle, nano- structured antimony oxides can be synthesized by various methods like vapor-solid route [24], hydrothermal [25], vapor condensation [26], sol-gel [27], X-ray radiation-oxidization route [28] and gas condensation [29].
Antimony oxides are chemically and toxico-logically distinct from antimony chlorides.
Antimony oxides, in combination with halogens, have been used as flame retardants in textiles since the 1960s.
(2003) reported antimony chloride as showing high estrogenicity, "antimony oxides--not antimony chloride--are used as catalysts in the manufacture of PET." Although Vasami asserts that antimony oxides "are chemically and toxicologically distinct from antimony chlorides," the toxicological literature does not provide strong support for this assertion.
Above-average gains will also occur for antimony oxides, which are used as synergists for halogenated compounds and for halogen-free phosphorus compounds substituted for others in response to environmental and health concerns.
