Description and Uses
Antimony (Sb) has been known since antiquity, and its early use as a cosmetic continues even today. Often mixed with lead or other heavy metals, this mascara-type cosmetic is known as kohl. Believed to possess powers to shield the eye from the sun and disease, it served purposes in both cosmetics and mysticism. Antimony has been found in many artifacts in the Middle East, and seems to have been used in the creation of small personal ornamentation or vessels.
Today the most common use of antimony is as an alloy metal with lead to make the leadharder. This lead–antimony alloy is used for electrical storage batteries, for sheathing for electricaland TV cables, in the making of wheel bearings, and as solder.
Although it is a brittle metal, it has found a use in the semiconductor industry in theproduction of diodes and infrared devices. It is also used to flameproof material and vulcanizerubber and can also be a component in paints, ceramic enamels, glass, pottery, andfireworks.
Antimony has few other uses except as an alloy to harden other materials. One recentdevelopment was to add antimony oxide to polyvinyl chloride (PVC pipe) to act as a flameretardant.
