Antimony sulfide was known for a long time. Some things plated with antimony and made out of antimony were found in Egypt and Chaldea. The first time antimony was mentioned in Europe was in the 1540. The first native antimony was found in Sweden in 1783. Antimony sulfide and antimony were confused sometimes in antiquity.
Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. The black form of this pigment, which occurs naturally as the mineral stibnite, was used as mascara and known as khol. The most famous user was the temptress Jezebel whose exploits are recorded in the Bible.
(i) For antimony sulfide selenide absorbers with a higher sulfur content: a, and b, the V oc is higher, 0.6 V, compared with that of cell c, 0.5 V. Conversely, J sc is lower at nearly 17 mA/cm 2 for the former, and 25 mA/cm 2 for the latter.
From the solution of antimony sulfur salts pure Sb 2 S 3 is precipitated by acidification and this sulfide, separated from the solution by filtration, is leached with a ferric fluoborate based electrolyte which oxidizes sulfide into elemental sulfur and dissolves antimony as Sb 3+ fluoborate.

About Antimony Sulfide Antimony Trisulfide is a moderately water and acid soluble Antimony source for uses compatible with sulfates. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal.
The metal antimony was known to German chemist Andreas Libavius in 1615 who obtained it by adding iron to a molten mixture of antimony sulfide, salt and potassium tartrate. This procedure produced antimony with a crystalline or starred surface.
Antimony is a chemical element with Sb as its symbol. It belongs to group 15, periodic number 5 of the periodic table. The metallic form of this element is bright, silvery, and brittle. The Mohs scale for hardness is 3 for this metal. It is a poor conductor of heat and electricity.
