On this page I'll provide comprehensive data for Antimony. I hope you profit from it.
Antimony Overview
Name Origin
Greek: anti and monos (not alone); symbol from mineral stibnite.
Symbol
Sb (Antimony)Description
Hard, brittle, silvery-white semimetal.
Discovery
Discovered By: Known to the ancients.
Year: Unknown
Location: Unknown
Sources
Found in stibnite (Sb2S3) and in valentinite (Sb2O3).
Uses
It is alloyed with other metals to increase their hardness. Also in the manufacture of a few special types of semiconductor devices. Also in plastics and chemicals. A few kinds of over-the-counter cold and flu remedies use antimony compounds.
