Reactions for Antimony Pentoxide Powder
When heated at 700°C the yellow hydrated pentoxide converts to an anhydrous white solid with a formula Sb2O13 containing both Sb(III) and Sb(V). Heating at 900°C produces a white insoluble powder of SbO2 of both α and β forms. The β form consists of Sb(V) in octahedral interstices and pyramidal Sb(III) O4 units. In these compounds, Sb(V) atom is octahedrally coordinated to six –OH groups.

What is Antimony Pentoxide Powder used for?
Antimony Pentoxide is used as a Flame retardant in clothing. It finds use as a flame retardant in ABS and other plastics and as a flocculant in the production of titanium dioxide, and is sometimes used in the production of glass, paint. It is also used as an ion exchange resin for a number of cations in acidic solution including Na+ (especially for their selective retentions), and as a polymerization and oxidation catalyst.
