Antimony Pentoxide Powder

High Purity Antimony(V) Oxide Powder Antimony(V) Oxide or Antimony Pentoxide is  is a highly insoluble thermally stable Antimony source suitable for glass, optic and ceramic applications. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity.

About Antimony Pentoxide Powder

Sb2O5 Molecular weight: 323.52, White or light yellow powder or particle, density1.5~2.0.  relative weight: 3.78; When heated up, first become Sb3O16,then become antimony quadoxide and then become antimony trioxide; slightly soluble in water and can make litmus paper turn red; slightly soluble in acid hydrochloride and calcium hydroxide; become white powder when combined with water; become waterless matter after heated. 


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.
