Antimony | U.S. Geological Survey
Antimony is an important mineral commodity used widely in modern industrialized societies. The element imparts strength, hardness, and corrosion resistance to alloys that are used in many areas of industry, including in lead-acid storage batteries. Antimony's leading use is as a fire retardant in safety equipment and in goods, such as mattresses.
