Tarihi
One of antimony's minerals, stibnite was recognized in predynastic Egypt as an eye cosmetic as early as about 3100 BC.
The first European description of a procedure for isolating antimony is in the book De la pirotechnia of 1540 by Vannoccio Biringuccio.
The first natural occurrence of pure antimony in the Earth's crust was described by the Swedish scientist and local mine district engineer Anton von Swab in 1783.

Uygulamalar
The largest applications for metallic antimony are as alloying material for lead and tin and for lead antimony plates in lead-acid batteries.
Alloying lead and tin with antimony improves the properties of the alloys which are used in solders, bullets and plain bearings.
Antimony trioxide is used as a flame retardant in adhesives, plastics, rubber and textiles.
