Antimony trisulfide

<p>Antimony trisulfide (Sb2S3) is found in nature as the crystalline mineral <a href="/facts/Stibnite/f1wo26vQ">stibnite</a> and the amorphous red mineral (actually a mineraloid) metastibnite. It is manufactured for use in <a href="/facts/Safety_match/EQPsJa7J">safety matches</a>, military ammunition, explosives and fireworks. It also is used in the production of ruby-colored glass and in plastics as a flame retardant. Historically the stibnite form was used as a grey pigment in paintings produced in the 16th century. In 1817, the dye and fabric chemist, <a href="/facts/John_Mercer_(scientist)/r1IhnAFv">John Mercer</a> discovered the <a href="/facts/Non-stoichiometric_compound/DAssoN0e">non-stoichiometric compound</a> Antimony Orange (approximate formula Sb2S3·Sb2O3), the first good orange pigment available for <a href="/facts/Textile_printing/NBvJSK5H">cotton fabric printing.</a>
</p><p>Antimony trisulfide was also used as the image sensitive <a href="/facts/Photoconductor/kPVR5C44">photoconductor</a> in <a href="/facts/Vidicon/eVaJgDlD">vidicon</a> camera tubes. It is a <a href="/facts/Semiconductor/zFf3mGTE">semiconductor</a> with a direct band gap of 1.8–2.5 eV. With suitable doping, <a href="/facts/Extrinsic_semiconductor/d9GPL5tV">p and n type</a> materials can be produced.
