Bismuth (III) sulfide is a chemical compound made from bismuth and sulfur .

Occurrence

Bismuth sulfide occurs naturally in the mineral bismuthinite . It is believed that it also occurs as a thin layer on the mountains of Venus .

Extraction and presentation

Bismuth sulfide can be produced in a precipitation reaction from bismuth (III) salts with a hydrogen sulfide solution.

{\ displaystyle {\ ce {2Bi ^ {3} + + 3H2S -> Bi2S3 + 6H +}}}

properties

Bismuth sulfide has an orthorhombic crystal structure with the space group Pnma (space group no. 62) and the lattice parameters a = 11.269 Å , b = 3.972 Å and c = 11.129 Å. In addition, with 1.6 · 10 ^{−72 it has} one of the smallest solubility products of all chemical compounds. Template: room group / 62

use

Bismuth sulfide as a mineral is used as a raw material for the production of bismuth. It is also used as an additive in brake linings , as a catalyst , as a component of flux in arc welding and as a component in the ignition charges of ammunition . Bismuth sulfide thin films and nanotubes are currently being researched as high-performance catalysts.
