Antimony is available as High Purity (99.999%) Antimony Oxide (Sb2O3) 

Powdermetal and compounds with purities from 99% to 99.9999% (ACS grade to 

ultra-high purity); metals in the form of foil, sputtering target, and rod, and 

compounds as submicron and nanopowders. Antimony trioxide is an insoluble 

form of antimony available in forms including powders and dense pellets for such 

uses as optical coating and thin film applications. Antimony fluorides are another 

insoluble form for uses in which oxygen is undesirable such as metallurgy, 

chemical and physical vapor deposition and in some optical coatings. Antimony is 

available in soluble forms including chlorides, nitrates and acetates. These 

compounds are also manufactured as solutions at specified stoichiometries.
