What is Antimony and its uses?
Antimony is a shiny silver metalloid, an element that’s almost but not quite a metal. It’s often used to harden and strengthen actual metals, like lead. And though it’s best known for its use in ammunition and flame retardants, it’s also in a long list of other products, including smartphones and batteries.
Antimony is used to increase the hardness of alloys, with lead alloys for batteries, with lead/copper/tin alloys for machine bearings. It is also used in automotive clutch and brake parts. The other major use is as antimony trioxide which is used for the production of flame retardant chemicals.
