它可以用作中子源。比穩(wěn)定同位素Sb輕的同位素傾向于發(fā)生β衰變，而較重的同位素更易發(fā)生β衰變。當然也有一些例外。銻化合物通常分為+3價和+5價兩類。與同主族的砷一樣，它的+5氧化態(tài)更為穩(wěn)定。氧化物與氫氧化物；三氧化二銻可由銻在空氣中燃燒制得。在氣相中，安徽銻回收，它以雙聚體SbO的形式存在，但冷凝時會形成多聚體。五氧化二銻只能用濃硝酸氧化三價銻化合物制得。銻也VV能形成混合價態(tài)化合物——四氧化二銻，其中的銻為Sb(III)和Sb(V)。與磷和砷不同的是，這些氧化物都是兩性的，它們不形成定義明確的含氧酸，而是與酸反應形成銻鹽。作用：氫氧化物曾廣用作溶劑、滅火劑、有機物的氯化劑、香料的浸出劑、纖維的脫脂劑、糧食的蒸煮劑、藥物的萃取劑、有機溶劑、織物的干洗劑，但是由于毒性的關系現(xiàn)在甚少使用并被限制生產(chǎn)，很多用途也被銅鋅合金等所替代，安徽銻回收。也可用來合成三氧化二銻、尼龍7、尼龍9的單體；還可制三氯甲烷和藥物；金屬切削中用作潤滑劑。鹵化物：銻能形成兩類鹵化物——SbX和SbX。其中三鹵化物（SbF，安徽銻回收、SbCl、SbBr和SbI）的空間構型都是三角錐形。三氟化銻可以由三氧化二銻與氫氟酸反應制得：Sb2O3+6HF→2SbF3+3H2O；這種氟化物是路易斯酸。銀白色有光澤硬而脆的金屬（常制成棒、塊、粉等多種形狀）。安徽銻回收</p><div

酒石酸銻鉀（俗稱吐酒石）曾用作修復血吸蟲病的藥物。它後來逐漸被吡喹酮所取代。銻及其化合物用於多種獸醫(yī)藥劑，例如安修馬林（硫蘋果酸銻鋰）用作反芻動物的皮膚調節(jié)劑。銻對角質化的組織有滋養(yǎng)和調節(jié)作用，至少對動物是如此。在一些安全火柴的火柴頭中使用了三硫化二銻。銻-124和鈹一起用於中子源：銻-124釋放出伽馬射線，引發(fā)鈹?shù)墓庵峦懽?。這樣釋放出的中子平均能量為24keV。銻的硫化物已被證實可以穩(wěn)定汽車剎車片材料的摩擦系數(shù)。銻也用於制造道具和道具示蹤劑。這種元素也用於傳統(tǒng)的裝飾中，例如刷漆和藝術玻璃工藝。20世紀30年代前曾用它作牙釉質的遮光劑，但是多次發(fā)生中毒後就不再使用銻[1]在地殼中的含量為，主要以單質或bai輝銻礦、方銻礦、銻華和銻赭石的形式存在，目前已知的含銻礦物多達120種。銻質堅而脆，銻鎢礦山容易粉碎，有光澤，無延性和展性。銻具有黃銻、灰銻、黑銻三種同素異形體。金屬銻呈銀白色，性脆，有獨特的熱縮冷脹性。無定形銻呈灰色，可由鹵化銻電解制得。銻有兩種同素異形體：黃色變體*在零下90℃以下才穩(wěn)定；金屬變體是銻的穩(wěn)定形式。2070℃時銻蒸汽為單原子分子。金屬銻不是一種活潑性很強的元素，它*在赤熱時與水反應放出氫氣。安徽銻回收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

曾有許多人患有癩病，他們試圖服用含銻的輝銻礦來修復?？墒窃S多服用輝銻礦的僧侶不但沒有恢復健康，反而病情惡化，一個個地死去。銻在地殼中的含量為，主要以單質或輝銻礦、方銻礦、銻華和銻赭石的形式存在，已知的含銻礦物多達120種。銻質堅而脆，容易粉碎，有光澤，無延性和展性N。銻具有黃銻、灰銻、黑銻三種同素異形體。金屬銻呈銀白色，性脆，有獨特的熱縮冷脹性。無定形銻呈灰色，可由鹵化銻電解制得。銻錠有兩種同素異形體：黃色變體只在零下90℃以下才穩(wěn)定；金屬變體是銻的穩(wěn)定形式。2070℃時銻蒸汽為單原子分子。金屬銻不是一種活潑性很強的元素，它只在赤熱時與水反應放出氫氣，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非金屬化合。銻易溶于熱硝酸，形成水合的氧化銻。能與熱硫酸反應，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。公元前16世紀。色素的黑色形式，天然地作為礦物輝銻礦出現(xiàn)，曾被作為睫毛膏和化妝墨使用。很有名的使用者是在圣經(jīng)中記錄的婦女Jezebel。另一種天然燃料被迦勒底文明知曉，其繁榮于時下是伊拉克南部的地區(qū)，于公元前6世紀和7世紀，它就是黃色的銻酸鉛。</p><p> 能結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)時的空間構型為三角雙錐形。但是轉化為液態(tài)后，五氟化銻形成聚合物，而五氯化銻依舊是單體。五氟化銻是很強的路易斯酸，可用于配制有名的強很酸氟銻酸（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酰化合物，例如SbOCl和(SbO)SO。銻化物、氫化物與有機銻化合物：這類化合物通常被視作Sb的衍生物。Sb金屬性不強，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，所以共價鍵很本質的分類方式就是它們的重疊方式。σ鍵，π鍵，δ鍵在有機化合物中，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。但無機銻化物不用此法。原因是，無機銻化物中經(jīng)常出現(xiàn)的共軛體系。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

是生產(chǎn)蓄電池極板、化工管道、電纜包皮的優(yōu)先材料；銻與錫、鉛、銅的合金強度高、極耐磨，是制造軸承、齒輪的好材料，高純度銻及其它金屬的復合物(如銀銻、鎵銻）是生產(chǎn)半導體和電熱裝置的理想材料。銻的化合物銻白是優(yōu)良的白色顏料，常用在陶瓷、橡膠、油漆、玻璃、紡織及化工產(chǎn)業(yè)。隨著科學技術的發(fā)展，銻現(xiàn)在已被廣用于生產(chǎn)各種阻燃劑、搪瓷、玻璃、橡膠、涂料、顏料、陶瓷、塑料、半導體元件、煙花、醫(yī)藥及化工等部門產(chǎn)品。銻資源分布世界目前已探明的銻礦儲量為400多萬噸，中國占了一半多。中國銻的儲量、產(chǎn)量、出口量在世界上均占有重要地位。中國目前有銻產(chǎn)地111處。主要包括貴州萬山、務川、丹寨、銅仁、半坡；湖南省新晃等汞礦，湖南省冷水江市錫礦山、板溪；廣西壯族自治區(qū)南丹縣大廠礦山；甘肅省崖灣銻礦、陜西省旬陽汞銻礦。銻的毒性銻會刺激人的眼、鼻、喉嚨及皮膚，持續(xù)接觸可破壞心臟及肝臟功能，吸入高含量的銻會導致銻中毒，癥狀包括嘔吐、頭部不適、呼吸困難，嚴重者可能死亡。德國音樂神童莫扎特死因不明，有一派說法就說他死于銻中毒。國際氧化銻工業(yè)協(xié)會早年運行的試驗表明，老鼠若長時間暴露在含銻高濃度空氣中，肺部會產(chǎn)生炎癥，近而染上肺不適。美國環(huán)境保護署限制排入湖、河、棄置場和農田的鎘量并禁止殺蟲劑中含有銻。安徽銻回收</p><p

一些無鉛焊接劑含有5%的銻）、鉛錫銻合金、以及硬化制作管風琴的含錫較少的合金。[13]銻其他應用其他的銻幾乎都用在下文所述的三個方面。較好項應用是生產(chǎn)聚對苯二甲酸乙二酯的穩(wěn)定劑和催化劑。第二項應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；這是因為銻離子與氧氣接觸后阻礙了氣泡繼續(xù)生成。第三項應用則是顏料。銻在半導體工業(yè)中的應用正不斷發(fā)展，主要是在超高電導率的n-型硅晶圓中用作摻雜劑，這種材料用于生產(chǎn)二極管、紅外線探測器和霍爾效應元件。20世紀50年代，小珠裝的鉛銻合金用于給NPN型合金結晶體管的發(fā)射器和儀器上漆。銻化銦是用于制作中紅外探測儀的材料。銻的生物學或醫(yī)學應用很少。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）用作反芻動物的皮膚調節(jié)劑。銻對角質化的組織有滋養(yǎng)和調節(jié)作用，至少對動物是如此。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。安徽銻回收</p><p
