Chemistry of Antimony (Z=51)

Antimony trisulfide. Antimony trisulfide, (Sb_2S_3), is a sulfide mineral commonly called stibnite or antimonite. Antimony trisulfide exists as a gray/black crystalline solid (orthorhombic crystals) and an amorphous red-orange powder. It turns black due to oxidation by air. Antimony trisulfide is the most important source for antimony.
