Antimony sulfate, Sb2(SO4)3, is a hygroscopic salt formed by reacting antimony or its compounds with hot sulfuric acid. It is used in doping of semiconductors and in the production of explosives and fireworks.
Solid antimony sulfate contains infinite ladders of SO4 tetrahedra and SbO3 pyramids sharing corners. It is often described as a mixed oxide, Sb2O3.3SO3.
Antimony sulfate is sometimes called a "salt" as it can be produced from the reaction of antimony and sulfuric acid, but antimony does not form a nitrate when dissolved in nitric acid, (an oxidising acid) but produces a mixture of antimony oxides, and this contrasts with bismuth which dissolves in both acids to form salts. It is deliquescent, and soluble in acids. It can be prepared by dissolving antimony, antimony trioxide, antimony trisulfide or antimony oxychloride in hot, concentrated sulfuric acid.
