Antimony is a silvery white, crystalline, brittle element, and has a high lustre. It is a metalloid, which while having the appearance of a metal, does not react chemically as a metal would. It is found in the ores stibnite (Sb2S3) and valentinite (Sb2O3).
The elemental symbol for antimony is Sb for Stibium. This is from the Greek stibi to mark it was used for blackening eyebrows and eyelashes. According to Hoover''s notes to the English translation of De Re Metallica, in St. Jerome''s translation of the Bible the cosmetic used by Jezebel (II. KINGS IX, 30) and by the Lady mentioned by Ezekiel (XXII, 40), "who didst wash thyself and paintedst thine eyes" is specifically given as stibio. He goes on to remark, that in any event the metal is clearly mentioned by Dioscorides (1st Century), who calls it stimmi and Pliny, who termed it stimmium.
Highly pure antimony is used to make semiconductor devices including diodes and infrared detectors.
