Antimony was recognized in compounds by the ancients and was known as a metal at the beginning of the 17th century andpossibly much earlier. It is not abundant, but is found in over 100 mineral species. It is sometimes found native, but more frequently as the sulfide,stibnite (Sb2S3); it is also found as antimonides of the heavy metals, and as oxides. It is extracted from the sulfide by roasting to the oxide, which isreduced by salt and scrap iron; from its oxides it is also prepared by reduction with carbon. Two allotropic forms of antimony exist: the normal stable,metallic form, and the amorphous gray form. The so-called explosive antimony is an ill-defined material always containing an appreciable amountof halogen; therefore, it no longer warrants consideration as a separate allotrope. The yellow form, obtained by oxidation of stibine, SbH3, is probablyimpure, and is not a distinct form. Natural antimony is made of two stable isotopes, 121Sb and 123Sb. Forty four other radioactive isotopes and isomersare now recognized. Metallic antimony is an extremely brittle metal of a flaky, crystalline texture. It is bluish white and has a metallic luster. It is notacted on by air at room temperature, but burns brilliantly when heated with the formation of white fumes of Sb2O3. It is a poor conductor of heat andelectricity, and has a hardness of 3 to 3.5. Antimony, available commercially with a purity of 99.999 + %, is finding use in semiconductor technologyfor making infrared detectors, diodes, and Hall-effect devices. Commercial-grade antimony is widely used in alloys with percentages ranging from1 to 20. It greatly increases the hardness and mechanical strength of lead. Batteries, antifriction alloys, type metal, small arms and tracer bullets, cablesheathing, and minor products use about half the metal produced. Compounds taking up the other half are oxides, sulfides, sodium antimonate, andantimony trichloride. These are used in manufacturing flame-proofing compounds, paints, ceramic enamels, glass, and pottery. Tartar emetic (hydratedpotassium antimonyl tartate) has been used in medicine. Antimony and many of its compounds are toxic. Antimony costs about $1.30/kg or about $12/g (99.999%). 1
