What is Antimony Used for – Metal Items

Antimony, the 51st element on the periodic table (symbol: Sb), is a shiny, silver-gray metal that has been used by mankind for millennia. Relatively rare, it is sometimes found as a base metal, but more often occurs bound to other elements in one of up to 100 mineral compounds. The most common of these is the sulfide stibnite (Sb₂S₃), which ...
