Antimony

Antimony is a chemical element with the symbol Sb and an atomic number of 51. A silvery lustrous grey metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds are prominent fire retardants found in many commercial and domestic products. Certain alloys are valuable for use in solders and ball bearings. An emerging application is the use of antimony in microelectronics. The relatively high toxicity of some antimony compounds, being similar to arsenic compounds, limits the applications. Certain compounds of antimony have been of fundamental value in chemistry, a prominent example being the development of superacids derived from antimony pentafluoride.
