Overview
Antimony is a brittle metalloid with metalloid properties used in alloys and flame retardant compounds.
Properties
It forms +3 and +5 oxidation states, produces hard alloys with lead and has semiconductor applications in some compounds.
Occurrence and Uses
Antimony is mined from stibnite and used in flame retardants, lead alloys, batteries and semiconductor devices.
Isotopes and Safety
Stable isotope Sb 121 and Sb 123 exist; antimony compounds can be toxic and require occupational controls.
