Description
Hard, brittle, silvery-white semimetal.
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.
Sources
Found in stibnite (Sb2S3) and in valentinite (Sb2O3).
Pronounciation (English)
