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.
Antimony
Antimony is also alloyed with tin to make pewter items such as plates, pitchers and cups, used mostly for decoration. One use of antimony, which is declining, is to make type metal for newspapers and magazines. Antimony is one of very few substances (bismuth and water are two others) which expand when it cools and freezes.
