Antimony (Sb)
MATERIAL
OVERVIEW
(Gr. anti plus monos - "a metal not
found alone") Antimony was recognized in compounds by the ancients and was
known as a metal at the beginning of the 17th century and possibly much earlier.
Antimony is not abundant, but is found in over 100 mineral
species. It is sometimes found natively, but more frequently it is found as the
sulfide stibnite.
Antimony is a poor conductor of heat and electricity.
Antimony and many of its compounds are toxic.
Antimony is finding use in semiconductor technology for
making infrared detectors, diodes and Hall-effect devices. It greatly increases
the hardness and mechanical strength of lead. Batteries, antifriction alloys,
type metal, small arms and tracer bullets, cable sheathing, and minor products
use about half the metal produced. Compounds taking up the other half are
oxides, sulfides, sodium antimonate, and antimony trichloride. These are used in
manufacturing flame-proofing compounds, paints ceramic enamels, glass, and
pottery.
