雖然至今尚未出現(xiàn)因吸入過量銻而染上肺不適的個案，但仍不排除其對人體的潛在危險。2002年9月，世界衛(wèi)生組織規(guī)定，對水中銻含量和日攝入量應小于。日本限定寶特瓶中的銻含量應小于200ppm，對熱灌裝用的飲料，則禁用含銻的寶特瓶。歐盟則規(guī)定，食品中的銻含量應小于20ppb，環(huán)保極PET纖維中的銻含量不得大于260ppm。元素輔助資料銻在地殼中含量是比較少的，但它在自然界中有單質(zhì)狀態(tài)存在。1777年，德國采礦官員包恩在西班包根（siebenbürgen）發(fā)現(xiàn)天然銻。把這種輝銻礦焙燒后，變成氧化物，再用碳還原，就可獲得金屬銻：2Sb2S3+9O2→2Sb2O3+6SO2↑Sb2O3+3C→2Sb+3CO↑60%的銻用於生產(chǎn)阻燃劑，而20%的銻用於制造電池中的合金材料、滑動軸承和焊bai接劑。銻的**主要用途是它的氧化物三氧化二銻用於制造耐火材料。除了含鹵素的聚合物阻燃劑以外，它幾乎總是與鹵化物阻燃劑一起使用。三氧化二銻形成銻的鹵化物的過程可以減緩燃燒，即為它具有阻燃效應的原因。這些化合物與氫原子、氧原子和羥基自由基反應，**終使火熄滅。商業(yè)中這些阻燃劑應用於兒童服裝、玩具、飛機和汽車座套。它也用於玻璃纖維復合材料（俗稱玻璃鋼）工業(yè)中聚酯樹脂的添加劑，例如輕型飛機的發(fā)動機蓋。</p><p> 但用那種材料制成的都是小飾物。這大削弱了銻在古代技術下具有可塑性這種說法的可信度。歐洲人萬諾喬·比林古喬于1540年很早在《火焰學》（）中描述了提煉銻的方法，這早于1556年阿格里科拉出版的名作《論礦冶》（）。此書中阿格里科拉錯誤地記入了金屬銻的發(fā)現(xiàn)。1604年，德國出版了一本名為《CurrusTriumphalisAntimonii》（直譯為“凱旋戰(zhàn)車銻”）的書，其中介紹了金屬銻的制備。15世紀時，據(jù)說筆名叫巴西利厄斯·華倫提努的圣本篤修會的修士提到了銻的制法，如果此事屬實，就早于比林古喬。一般認為，純銻是由賈比爾（JābiribnHayyān）于8世紀時很早制得的。然而爭議依舊不斷，翻譯家馬塞蘭·貝特洛聲稱賈比爾的書里沒有提到銻，但其他人認為貝特洛只翻譯了一些不重要的著作，而很相關的那些（可能描述了銻）還沒翻譯，它們的內(nèi)容至今還是未知的。地殼中自然存在的純銻很早是由瑞典籍英國科學家威廉·亨利·布拉格于1783年記載的。品種樣本采集自瑞典西曼蘭省薩拉市的薩拉銀礦。根據(jù)英國地質(zhì)調(diào)查局2005年的報告，中華人民國家是世界上銻產(chǎn)量很大的國家，占了全球的84%，遠遠超出其后的南非、玻利維亞和塔吉克斯坦。湖南省冷水江市的錫礦山是世界很大銻礦。銻在室溫下的空氣中是穩(wěn)定的，但加熱時能與氧氣反應生成三氧化二銻。</p><div

在室溫中不會被空氣氧化，但能與氟、氯、溴化合；加熱時才能與碘和其他百金屬化合。銻易溶于熱硝酸，形成水合的氧化銻。能與熱硫反應，生成硫酸銻。銻在高溫時可與氧反應，生成三氧化二銻，為兩性氧化物，難溶于水，但溶于酸和堿；可與濃硝酸反應。銻多用作其它合金的組元，可增加其硬度和強度。如蓄電池極板、軸承合金、印刷合金（鉛字）、焊料、電纜包皮及道具彈中都含銻。鉛錫銻合金可作薄板沖壓模具。高純銻是半導體硅和鍺的摻雜元素。銻白（三氧化二銻）是銻的主要用途之一，銻白是搪瓷、油漆的白色顏料和阻燃劑的重要原料。硫化銻（五硫化二銻）是橡膠的紅色顏料。生銻（三硫化二銻）用于生產(chǎn)火柴和煙劑。銻是電和熱的不良導體，在常溫下不易氧化，有抗腐蝕性能。因此，銻在合金中的主要作用是增加硬度，常被稱為金屬或合金的硬化劑。在金屬中加入比例不等的銻后，金屬的硬度就會加大，可以用來制造軍火。銻及銻化合物首先使用于耐磨合金、印刷鉛字合金及軍火工業(yè)，是重要的戰(zhàn)略物資。銻可用作PET生產(chǎn)中的縮聚催化劑。含銻合金及化合物則用途十分廣，銻化物可阻燃，所以常應用在各式塑料和防火材料中。含銻、鉛的合金耐腐蝕。易溶于王水，溶于濃硫酸。相對密度6.68。熔點630℃。沸點1635℃(1440℃)。南寧高純銻粒廢料回收</p><p
