地殼中自然存在的純銻很早是由瑞典籍英國科學(xué)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。[5]銻應(yīng)用編輯60%的銻用于生產(chǎn)阻燃劑，而20%的銻用于制造電池中的合金材料、滑動軸承和焊接劑。銻阻燃劑銻的很主要用途是它的氧化物三氧化二銻用于制造耐火材料。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(yīng)的原因。這些化合物與氫原子、氧原子和羥基自由基反應(yīng)，很終使火熄滅。商業(yè)中這些阻燃劑應(yīng)用于兒童服裝，山東6N銻?；厥?、玩具、飛機(jī)和汽車座套。它也用于玻璃纖維復(fù)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(jī)的發(fā)動機(jī)蓋。樹脂遇火燃燒但火被撲滅后它的燃燒就會自行停止。[12]銻合金銻能與鉛形成用途廣的合金，山東6N銻?；厥眨@種合金硬度與機(jī)械強(qiáng)度相比銻都有所提高。大部分使用鉛的場合都加入數(shù)量不等的銻來制成合金。在鉛酸電池中，這種添加劑改變電極性質(zhì)，并能減少放電時副產(chǎn)物氫氣的生成，山東6N銻?；厥铡ｄR也用于減摩合金（例如巴比特合金），道具、鉛彈、網(wǎng)線外套、鉛字合金（例如Linotype排字機(jī)）、焊料。美國食品和藥物管理局規(guī)定食用色素的含銻量為不得多于15ppm。山東6N銻粒回收</p><div

能結(jié)合氟離子形成配離子SbF和SbF。熔化的三氟化銻是一種弱的導(dǎo)體。三氯化銻則由三硫化二銻溶于鹽酸制得：Sb2S3+6HCl→2SbCl3+3H2S五鹵化物（SbF和SbCl）氣態(tài)時的空間構(gòu)型為三角雙錐形。但是轉(zhuǎn)化為液態(tài)后，五氟化銻形成聚合物，而五氯化銻依舊是單體。五氟化銻是很強(qiáng)的路易斯酸，可用于配制有名的強(qiáng)很酸氟銻酸（HSbF）。銻的鹵氧化物比砷和磷更為常見。三氧化二銻溶于濃酸再稀釋可形成銻?；衔铮鏢bOCl和(SbO)SO。銻化物、氫化物與有機(jī)銻化合物：這類化合物通常被視作Sb的衍生物。Sb金屬性不強(qiáng)，能與金屬形成銻化物，例如銻化銦（InSb），銻化銀（Ag3Sb），銻鈀礦(Pd5Sb2)，方銻金礦(AuSb2)，紅銻鎳礦(NiSb)等。堿金屬和鋅的銻化物，例如NaSb和ZnSb比以上物質(zhì)更為活潑。這些銻化物用酸處理可以生成不穩(wěn)定的氣體銻化氫（SbH）。銻化物一般以共價鍵鏈接，是電子云的重疊，所以共價鍵很本質(zhì)的分類方式就是它們的重疊方式。σ鍵，π鍵，δ鍵在有機(jī)化合物中，通常把共價鍵以其共用的電子對數(shù)分為單鍵、雙鍵以及三鍵。單鍵是一根σ鍵；雙鍵和三鍵都含一根σ鍵，其馀1根或2根是π鍵。但無機(jī)銻化物不用此法。原因是，無機(jī)銻化物中經(jīng)常出現(xiàn)的共軛體系。海南6N銻回收銻的同素異形體屬于六方晶系排布狀態(tài)，有一個6次對稱軸或者6次倒轉(zhuǎn)軸，該軸是晶體的直立結(jié)晶軸C軸。</p><div

洛斯基公司估計(jì)全球在2010年的次級生產(chǎn)銻產(chǎn)量為39,540噸。英國地質(zhì)調(diào)查局在2011年下半年將銻列在風(fēng)險列表較好位。這個列表表示如果化學(xué)元素不能穩(wěn)定供應(yīng)，會對維持英國經(jīng)濟(jì)和生活方式造成的相對風(fēng)險。根據(jù)洛斯基公司的報(bào)告，2014年中國的銻產(chǎn)量有所減少，并且在未來一段時間不可能上升。中國已沒有開發(fā)十年左右的重要銻礦床，這種重要的經(jīng)濟(jì)儲備資源將迅速枯竭。同時，歐盟在2011年的一份報(bào)告中也將銻列為12種關(guān)鍵的原料之一，主要是因?yàn)閬碜灾袊酝獾匿R產(chǎn)量很少。以下是洛斯基公司提供的2014年世界銻的主要生產(chǎn)者：2014年銻的主要生產(chǎn)者國家公司產(chǎn)量（噸/年）中國閃銻度礦業(yè)（前錫礦山閃星銻業(yè)）2,750玻利維亞許多5,460加拿大比弗·布魯克6,000中國布魯克投資集團(tuán)55,000中國湖南辰州礦業(yè)20,000中國華錫集團(tuán)20,000中國沈陽華昌銻業(yè)15,000哈薩克斯坦Kazzinc1,000吉爾吉斯斯坦Kadamdzhai500老撾SRS500墨西哥美國銻業(yè)70緬甸許多6,000俄羅斯GeoPDroMining6,500南非默奇森聯(lián)合公司6,000塔吉克斯坦YUnzob5,500泰國未知600儲量根據(jù)美國地質(zhì)調(diào)查局的統(tǒng)計(jì)數(shù)據(jù)，世界的銻礦藏將在13年內(nèi)枯竭。但美國地質(zhì)調(diào)查局期待這期間會發(fā)現(xiàn)更多銻礦。2010年的世界銻儲量全球1,831,000國家儲量。</p><p> 尤以三價化合物為常見，主要的有三硫化二銻、三氧化二銻、三氯化銻等。遷移轉(zhuǎn)化：天然水中銻的自然含量一般為～，平均為。海水中含銻量為～，平均為。銻在水中的遷移機(jī)制，有通過結(jié)晶礦物的遷移，有機(jī)螯合遷移、被吸附性離子遷移、與氧化物相締合的遷移，以及可溶性遷移。溶于水中的銻化合物有三氯化銻、硫酸銻、酒石酸銻和五氯化銻。銻在淡水中以五價銻存在。海水中的銻以絡(luò)合物形式存在，其主要配位體是羥基，下不為例上的形態(tài)為Sb(OH)6-或二聚物Sb2O(OH)4。受銻污染的土壤，銻一般富集在表層，主要是土壤表層無機(jī)和有機(jī)膠體的吸附作用。銻在土壤中是以+3、+5價狀態(tài)存在。在旱田或干土中，土壤處于氧化狀態(tài)，此時土壤中的Sb3+可氧化成Sb5+，銻以Sb5+存在居多。水田土壤處于淹沒還原狀態(tài)，土壤中的銻主要以Sb3+存在。危險特性：遇明火、高熱可燃。粉體與空氣可形成炸裂性混合物，當(dāng)達(dá)到一定的濃度時，遇火星會發(fā)生炸裂。與硝酸銨、二氟化溴、三氮化溴、氯酸、氧化氯、三氟化氯、硝酸、硝酸鉀、高錳酸鉀、過氧化鉀接觸能引起反應(yīng)。燃燒(分解)產(chǎn)物：氧化銻。3.現(xiàn)場應(yīng)急監(jiān)測方法:4.實(shí)驗(yàn)室監(jiān)測方法:5-Br-PADAP光度法；原子吸收法《水和廢水監(jiān)測分析方法》。易溶于王水，溶于濃硫酸。相對密度6.68。熔點(diǎn)630℃。沸點(diǎn)1635℃(1440℃)。</p><div
