Antimony | Sb - PubChem

Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing. However, there are companies in the United States that produce antimony ...

Antimony Trisulphide, Sb 2 S 3

Antimony Trisulphide, Sb 2 S 3, has been known from very early times, under a variety of names, such as antimonium crudum, grey antimony ore, antimony glance, antimony glass, stibnite.Until the eighteenth century it was frequently confused with antimony metal. It exists in at least three forms, a crystalline form and two amorphous forms, each of which may be obtained in a variety of ways.
