地殼中自然存在的純銻很早是由瑞典籍英國(guó)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(dòng)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(guò)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，哈爾濱銻廢料回收、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、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(dòng)機(jī)蓋。樹脂遇火燃燒但火被撲滅后它的燃燒就會(huì)自行停止。[12]銻合金銻能與鉛形成用途廣的合金，這種合金硬度與機(jī)械強(qiáng)度相比銻都有所提高，哈爾濱銻廢料回收。大部分使用鉛的場(chǎng)合都加入數(shù)量不等的銻來(lái)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(shí)副產(chǎn)物氫氣的生成。銻也用于減摩合金（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。銻（英語(yǔ)：Antimony，哈爾濱銻廢料回收，拉丁語(yǔ)：stibium）是一種有毒的化學(xué)元素，元素符號(hào)為Sb，原子序數(shù)為51。哈爾濱銻廢料回收</p><div

一些無(wú)鉛焊接劑含有5%的銻）、鉛錫銻合金、以及硬化制作管風(fēng)琴的含錫較少的合金。[13]銻其他應(yīng)用其他的銻幾乎都用在下文所述的三個(gè)方面。較好項(xiàng)應(yīng)用是生產(chǎn)聚對(duì)苯二甲酸乙二酯的穩(wěn)定劑和催化劑。第二項(xiàng)應(yīng)用則是去除玻璃中顯微鏡下可見的氣泡的澄清劑，主要用途是制造電視屏幕；這是因?yàn)殇R離子與氧氣接觸后阻礙了氣泡繼續(xù)生成。第三項(xiàng)應(yīng)用則是顏料。銻在半導(dǎo)體工業(yè)中的應(yīng)用正不斷發(fā)展，主要是在超高電導(dǎo)率的n-型硅晶圓中用作摻雜劑，這種材料用于生產(chǎn)二極管、紅外線探測(cè)器和霍爾效應(yīng)元件。20世紀(jì)50年代，小珠裝的鉛銻合金用于給NPN型合金結(jié)晶體管的發(fā)射器和儀器上漆。銻化銦是用于制作中紅外探測(cè)儀的材料。銻的生物學(xué)或醫(yī)學(xué)應(yīng)用很少。主要成分為銻的藥品稱作含銻藥劑（antimonial），是一種催吐劑。銻化合物也用作抗原蟲劑。從1919年起，酒石酸銻鉀（俗稱吐酒石）曾用作有用血吸蟲病的藥物。它后來(lái)逐漸被吡喹酮所取代。銻及其化合物用于多種獸醫(yī)藥劑，例如安修馬林（硫蘋果酸銻鋰）用作反芻動(dòng)物的皮膚調(diào)節(jié)劑。銻對(duì)角質(zhì)化的組織有滋養(yǎng)和調(diào)節(jié)作用，至少對(duì)動(dòng)物是如此。含銻的藥物也用作有用家畜的利什曼病的選擇之一，例如葡甲胺銻酸鹽?？上У氖?，它不只有用指數(shù)較低。哈爾濱銻廢料回收另外三個(gè)水平結(jié)晶軸正端互成120夾角。</p><div

但加熱時(shí)能與氧氣反應(yīng)生成三氧化二銻。銻是一種帶有銀色光澤的灰色金屬，其莫氏硬度為3。因此，純銻不能用于制造硬的物件：貴州省曾在1931年發(fā)行銻制的硬幣，但因?yàn)殇R很容易磨損，在流通過(guò)程損失嚴(yán)重。銻在一般條件下不與酸反應(yīng)。銻的同素異形體屬于六方晶系排布狀態(tài)(hexagonalcrystalsystem），有一個(gè)6次對(duì)稱軸或者6次倒轉(zhuǎn)軸，該軸是晶體的直立結(jié)晶軸C軸。另外三個(gè)水平結(jié)晶軸正端互成120夾角。軸角α=β=90，γ=120，軸單位a=b≠c，次性質(zhì)使得用尖銳的器具刮擦它就會(huì)發(fā)生放熱的化學(xué)反應(yīng)，放出白煙并生成金屬銻。如果在研缽中用研杵將它磨碎，就會(huì)發(fā)生劇烈的炸開。黑銻是由金屬銻的蒸汽急劇冷卻形成的，它的晶體結(jié)構(gòu)與紅磷和黑砷相同，在氧氣中易被氧化甚至自燃。當(dāng)溫度降到100℃時(shí)，它逐漸轉(zhuǎn)變成穩(wěn)定的晶型。黃銻是很不穩(wěn)定的一種，只能由銻化氫在-90℃下氧化而得。在這種溫度和環(huán)境光線的作用下，亞穩(wěn)態(tài)的同素異形體會(huì)轉(zhuǎn)化成更穩(wěn)定的黑銻。金屬銻的結(jié)構(gòu)為層狀結(jié)構(gòu)（空間群：），而每層都包含相連的褶皺六元環(huán)結(jié)構(gòu)。很近的和次近的銻原子形成變形八面體，在相同雙層中的三個(gè)銻原子比其他三個(gè)相距略近一些。這種距離上的相對(duì)近使得金屬銻的密度達(dá)到g/cm。易溶于王水，溶于濃硫酸。相對(duì)密度6.68。熔點(diǎn)630℃。沸點(diǎn)1635℃(1440℃)。哈爾濱銻廢料回收</p><p
