The amount of oxygen consumed during the reaction is critical to the antimony-arsenic separation. Historically the stibnite form was used as a grey pigment in paintings produced in the 16th century. In order to obtain a final antimony sulfide product possessing less than about 0.4 arsenic and recovering 95 of the antimony in solution, the ratio of the antimonate concentration to the arsenate concentration should be maintained at at least about two to one. It also is used in the production of ruby-colored glass and plastics as a flame retardant.

It is manufactured for use in safety matches, military ammunition, explosives, and fireworks. Prochemonline.Antimony trisulfide Sb2S3 is found in nature as the crystalline mineral stibnite and the amorphous red mineral metastibnite.
#Antimony sulfide skin
Safety Īntimony(III) sulfate causes irritation to the skin and mucous membranes. It is also used for coating anodes in electrolysis and in the production of explosives and fireworks. Owing to its solubility, antimony sulfate has uses in the doping of semiconductors. It can be prepared by dissolving antimony, antimony trioxide, antimony trisulfide or antimony oxychloride in hot, concentrated sulfuric acid. It is deliquescent, and soluble in acids. Chemical properties Īntimony 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 often described as a mixed oxide, Sb 2O 3.3SO 3. It is used in doping of semiconductors and in the production of explosives and fireworks. Solid antimony sulfate contains infinite ladders of SO 4 tetrahedra and SbO 3 pyramids sharing corners. Antimony sulfate, Sb 2 (SO 4) 3, is a hygroscopic salt formed by reacting antimony or its compounds with hot sulfuric acid.
