Description of Antimony Sulfide

Antimony is a bluish-white brittle metal. It has low thermal and electrical conductivity. Antimony is stable in air at room temperature, but forms antimony trioxide (Sb2O3) if heated. Upon melting, it can be used to strengthen and harden other metals. Antimony (III) sulfide is a gray powder. It occurs natively as stibnite, and can be obtained synthetically as a pigmented precipitate. It is insoluble in water, and reacts with hydrochloric acid to make hydrogen sulfide and an antimony (III) compound. It is also a semiconductor with a band gap of 1.8-2.5 eV.



Application of Antimony Sulfide

  • Used for military ammunition, safety matches, and fireworks. 
  • It is used as a flame retardant for the production of ruby-colored glass, brake pads, and plastics. 
  • Used as a pigment for cosmetic and camouflage purposes.
