金屬銻不是一種活潑性很強(qiáng)的元素，它只在赤熱時(shí)與水反應(yīng)放出氫氣，在室溫中不會(huì)被空氣氧化，但能與氟、氯、溴化合；加熱時(shí)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(yīng)，生成硫酸銻。銻在高溫時(shí)可與氧反應(yīng)，生成三氧化二銻，為兩性氧化物，難溶于水，攀枝花5N5銻回收，但溶于酸和堿；可與濃硝酸反應(yīng)。銻,元素符號(hào)Sb，原子序數(shù)51，原子量，外面電子排布5s25p3，位于第五周期第ⅤA族。共價(jià)半徑141皮米，bai離子半徑Sb-3245皮米，Sb+562皮米，首先電離能，電負(fù)性，主要氧化數(shù)(-3)、+3、+5。銻有幾種同素異形體。通常很穩(wěn)定的是灰銻，銀白或銀灰色菱形晶體，脆而硬，由液態(tài)凝固時(shí)體積膨脹，即有冷脹性，密度，熔點(diǎn)℃，沸點(diǎn)1750℃，銻蒸氣分子為Sb4，導(dǎo)電性差。此外還有灰色的無定形銻，黃色的黃銻，黑色的黑銻等。銻化學(xué)性質(zhì)不很活動(dòng)。室溫下不能被空氣中氧氣氧化，攀枝花5N5銻回收，但能跟氟、氯、溴化合生成三價(jià)或五價(jià)鹵化物。加熱時(shí)可跟碘，攀枝花5N5銻回收、硫化合。高溫時(shí)燃燒顯藍(lán)色并生成Sb4O6。常溫時(shí)不跟水反應(yīng)，紅熱時(shí)跟水反應(yīng)放出氫氣。跟熱硝酸反應(yīng)，生成水合氧化銻：6Sb+10HNO3+3xH2O=3Sb2O5·xH2O+10NO↑+5H2O能溶于熱的濃鹽酸和硫酸生成氯化銻和硫酸銻。與強(qiáng)堿反應(yīng)生成亞銻酸鹽。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。攀枝花5N5銻回收</p><div

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（一些無鉛焊接劑含有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。其他應(yīng)用：其他的銻幾乎都用在下文所述的三個(gè)方面。前列項(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）曾用作修復(fù)血吸蟲病的藥物。它后來逐漸被吡喹酮所取代。銻及其化合物用于多種藥劑，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。攀枝花5N5銻回收氧化物與氫氧化物；三氧化二銻可由銻在空氣中燃燒制得。</p><div

使中國(guó)的“連錫”轉(zhuǎn)入銻生產(chǎn)的時(shí)代。1908年湖南華昌公司從法國(guó)引進(jìn)揮發(fā)焙燒法，開始用此法煉銻。隨著機(jī)械制造業(yè)的興起，銻的用途和需求量擴(kuò)大，繼開發(fā)錫礦山之后又先后開發(fā)了湖南桃江板溪、新邵龍山、桃源沃溪等地銻礦，使湖南銻業(yè)居全國(guó)前面。接著，黔、滇、桂等省區(qū)也相繼開采一些銻礦。從1908年以后數(shù)十年間，中國(guó)產(chǎn)銻量常占世界總產(chǎn)量50%以上，只就錫礦山自1912—1935年間的銻品產(chǎn)量占世界產(chǎn)量的，占全國(guó)的。1942年中國(guó)有名的有色金屬冶金學(xué)家，世界很早的銻冶金**之一王寵佑與美國(guó)人霍德森(Hodson）共同取得飄浮熔煉—?dú)鈶B(tài)還原熔煉的專利權(quán)。新中國(guó)成立之后，對(duì)銻礦進(jìn)行了大的地質(zhì)勘探和開發(fā)，并發(fā)展了硫化銻精礦鼓風(fēng)爐揮發(fā)熔煉。中國(guó)銻礦儲(chǔ)量和產(chǎn)量均居世界**，并大量出口，生產(chǎn)高純度金屬銻（含銻）及質(zhì)量特級(jí)銻白，出席著世界銻業(yè)先進(jìn)生產(chǎn)水平。資源分布：世界時(shí)下已探明的銻礦儲(chǔ)量為400多萬(wàn)噸，中國(guó)占了一半多。2012年全球金屬銻總產(chǎn)量為18萬(wàn)噸，而2011年產(chǎn)量則為，中國(guó)金屬銻產(chǎn)量基本不變，維持在15萬(wàn)噸。中國(guó)銻的儲(chǔ)量、產(chǎn)量、出口量在世界上均占世界前列位。中國(guó)目前有銻產(chǎn)地171處。主要包括貴州萬(wàn)山、務(wù)川、丹寨、銅仁、半坡；。黃銻是很不穩(wěn)定的一種，只能由銻化氫在-90℃下氧化而得。</p><div

已知銻有四種同素異形體——一種穩(wěn)定的金屬銻和三種亞穩(wěn)態(tài)銻（炸開性銻、黑銻、黃銻）。金屬銻是一種易碎的銀白色有光澤的金屬。把熔融的銻緩慢冷卻，金屬銻就會(huì)結(jié)成三方晶系的晶體，其與砷的灰色同素異形體異質(zhì)同晶。罕見的炸開形狀的銻可由電解三氯化銻制得，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。[4]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，但層與層之間的成鍵很弱也造成它很軟且易碎。[3]同位素銻有兩種穩(wěn)定同位素，Sb的自然豐度為，而Sb的自然豐度為。銻還有35種放射性同位素，其中半衰期很長(zhǎng)的Sb為。此外，已發(fā)現(xiàn)了29種亞穩(wěn)態(tài)。銻的工業(yè)制法是先焙燒，再用碳在高溫下還原，或者是直接用金屬鐵還原輝銻礦。攀枝花5N5銻回收</p><p
