Antimony is a chemical element with symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.
Antimony also is used as an alloy, as it hardens other metals. An alloy with lead greatly improves strength and hardness of lead. It also is used in semiconductors, diodes, infrared detectors, batteries and bullets. Antimony compounds are used in paint pigments, enamels, glass, and pottery. The symbol for antimony, Sb, comes from antimonyâs Latin name stibium.
