We know that one of antimony&#8217;s minerals, stibnite (Sb<sub>2<\/sub>S<sub>3<\/sub>), was used in Egyptian cosmetics four or five thousand years ago as a black eyeliner. <sup>(1)<\/sup> <\/p>\n<p> It is likely that the Roman author Pliny used the name stibium in the first century AD. We get the modern element symbol for antimony, Sb, from the word stibium. According to Pliny, the mineral stibnite was found most commonly among silver ores.<\/p>\n<p> Pliny described how stibnite could be used as a medicine and how, if heated too strongly, it would turn to <a href=\"\/elements\/lead.html\">lead<\/a>. We understand now that the &#8216;lead&#8217; described by Pliny is actually the element antimony, produced by heating its ore. <sup>(2)<\/sup><\/p>\n<p> In the first half of the 1500s, Italian metallurgist Vannoccio Biringuccio wrote the alchemical work: &#8220;Concerning Antimony and Its Ore.&#8221; He describes antimony sulfide as either &#8220;a monstrosity among metals&#8221; or &#8220;a material that is about to reach metallic perfection, but is hindered from doing so by being mined too soon.&#8221; [This was not chemistry as we know it!]\n<\/p>\n<p> Biringuccio does get it right when he warns against heating antimony sulfide too strongly, because this will produce a substance that, &#8220;although this is very white and almost more shining than <a href=\"\/elements\/silver.html\">silver<\/a>, it is much more brittle than glass.&#8221; This is a clear description of the element antimony. <sup>(3)<\/sup><\/p>\n<p> Clearly alchemists had produced antimony in its elemental state by the 1500s.<\/p>\n<p> French chemist Nicolas L\u00e9mery wrote his Treatise on Antimony in 1707 and took a scientific leap \u2014 backwards. In his writings, L\u00e9mery describes how acids prick the tongue because they contain spiky particles, while metals dissolve in acids because the sharp points of acids tear the metal particles apart. <sup>(4)<\/sup><\/p>\n<p> The name &#8220;antimony&#8221; is derived from two Greek words: &#8216;anti&#8217; and &#8216;monos&#8217; which mean &#8216;not alone.&#8217; <\/p>\n<p> The name was given because antimony is rarely found native; it is usually combined with <a href=\"\/elements\/sulfur.html\">sulfur<\/a> or with heavier metals such as <a href=\"\/elements\/copper.html\">copper<\/a>, <a href=\"\/elements\/lead.html\">lead<\/a> and <a href=\"\/elements\/silver.html\">silver<\/a>.<\/p>\n<div style=\"clear:both; line-height:20px;\">&nbsp;<\/div>\n<div class=\"adsense300\">\n<div class=\"adsense300spacer\">\n<div style=\"line-height:10px;\">\n<img decoding=\"async\" alt=\"\" src=\"\/\/www.chemicool.com\/ad.png\"\/>\n<\/div>\n<p><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script><ins class=\"adsbygoogle\" style=\"display:inline-block;width:336px;height:280px\" data-ad-client=\"ca-pub-9461632227417539\" data-ad-slot=\"2986645201\"><\/ins><script>(adsbygoogle = window.adsbygoogle || []).push({});<\/script><\/p>\n<div class=\"leftimagepadding\">\n<p><iframe loading=\"lazy\" width=\"300\" height=\"225\" src=\"https:\/\/www.youtube.com\/embed\/kcc6qNT3BoU?rel=0\" allowfullscreen><\/iframe><\/p>\n<div class=\"youtubecaption\">\nAntimony was used as a catalyst in CFC production.\n<\/div>\n<p><iframe loading=\"lazy\" width=\"300\" height=\"225\" src=\"https:\/\/www.youtube.com\/embed\/RTE-WZ_lmiY?rel=0\" allowfullscreen><\/iframe><\/p>\n<div class=\"youtubecaption\">\nRotating 3D molecular model of antimony pentachloride.\n<\/div>\n<div style=\"width: 310px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.chemicool.com\/elements\/images\/300-antimony-trihydride.jpg\" width=\"300\" height=\"286\" alt=\"Stibine.\" class=\"size-full\" \/><p class=\"wp-caption-text\">Molecular model of the highly toxic stibine (antimony trihydride).

Many of the salts are carcinogenic.<\/p>\n<p>\t\tThe metallic form is considered to be less active whereas stibine (SbH<sub>3<\/sub>) and stibnite (Sb<sub>2<\/sub>S<sub>3<\/sub>) are extremely toxic.<sup>(5)<\/sup> Antimony is toxic and immediately dangerous to life or health at 50 mg m<sup>-3<\/sup> or above. <sup>(6)<\/sup><\/p>\n<p>\t\tExposure to 9 milligrams per cubic meter of air (mg\/m<sup>3<\/sup>) of antimony as stibnite for a long time can irritate your eyes, skin, and lungs. Breathing 2 mg\/m<sup>3<\/sup> of antimony for a long time can cause problems with the lungs (pneumoconiosis) heart problems (altered electrocardiograms), stomach pain, diarrhea, vomiting and stomach ulcers. People who drank over 19 ppm of antimony in one sitting vomited. <sup>(7)<\/sup><\/p>\n<p>\t  <strong>Characteristics:<\/strong><\/p>\n<p>\t\t Antimony is metalloid, so it has some metallic properties but not enough to be classified as a true metal.

It is easily powdered.<\/p>\n<p>\t\tAntimony also has the unusual property that (like water) it expands as it freezes.

The higher the proportion of antimony in the alloy, the harder and more brittle it will be. Alloys made with antimony expand on cooling, retaining the finer details of molds. Antimony alloys are therefore used in making typefaces for clear, sharp printing.<\/p>\n<p>\t Babbit metals, used for machinery bearings, are alloys of <a href=\"https:\/\/www.chemicool.com\/elements\/lead.html\">lead<\/a>, <a href=\"https:\/\/www.chemicool.com\/elements\/tin.html\">tin<\/a>, <a href=\"https:\/\/www.chemicool.com\/elements\/copper.html\">copper<\/a> and antimony.
