銻可以用鐵屑從天然硫化銻中還原并分離出來：Sb2S3+3Fe→2Sb+3FeS三硫化二銻比三氧化二銻穩(wěn)定，因此易于轉化，而焙燒后又恢復成硫化物。這種材料直接用于許多應用中，可能產(chǎn)生的雜質是砷和硫化物。將銻從氧化物中提取出來可使用碳的熱還原法：2Sb2O3+3C→4Sb+3CO2低品味的礦石在高爐中還原，而高品味的則在反射爐中還原。應用：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。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的原因。這些化合物與氫原子、氧原子和羥基自由基反應，很終使火熄滅。商業(yè)中這些阻燃劑應用于兒童服裝、玩具、飛機和汽車座套。它也用于玻璃纖維復合材料（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。樹脂遇火燃燒但火被撲滅后它的燃燒就會自行停止。合金：銻能與鉛形成用途廣的合金，這種合金硬度與機械強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。</p><p> 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，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)。一些銻的金屬互化物是化學反應中的優(yōu)良催化劑?？纱呋拿骟w烷轉化為乙烯基乙炔的反應和氫化銨的分解反應。隨著科學技術的發(fā)展，銻時下已被廣用于生產(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。銻在地殼中含量是比較少的，但它在自然界中部分以單質狀態(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↑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。因此，純銻不能用于制造硬的物件。</p><div

并能減少放電時副產(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）、焊料（一些無鉛焊接劑含有5%的銻）、鉛錫銻合金、以及硬化制作管風琴的含錫較少的合金。其他應用：其他的銻幾乎都用在下文所述的三個方面。前列項應用是生產(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）曾用作修復血吸蟲病的藥物。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。目前已知銻化合物在古代就用作化妝品，金屬銻在古代也有記載，但那時卻被誤認為是鉛。山西5N銻加工</p><p

主要用于制合金如印刷用的活字合金、硬質合金、巴氏合金。還用于制銻鹽、醫(yī)藥、顏料及半導體材料等。古代已應用銻及其化合物。在自然界中有游離態(tài)和化合態(tài)兩種形式存在，主要礦物有輝銻礦(Sb2S3)和方銻礦(Sb2O3)。在地殼中的豐度為×10-4％。用輝銻礦跟鐵屑共熱，或用三氧化二銻與碳共熱都可還原出銻。金屬銻性質：第15族(VA)主族準金屬元素。原子序數(shù)51。穩(wěn)定同位素121，123。密度(20℃)。熔點℃(3。沸點1587℃。氧化態(tài)0，-3，+3，+5。銻有兩種同素異形體：正常穩(wěn)定的金屬銻和非晶態(tài)的灰銻。金屬銻呈藍白色，具有金屬光澤，質地硬而脆。室溫下不與干燥空氣作用。受熱時燃燒生成三氧化二銻白煙。不與稀酸和堿作用。主要礦物有輝銻礦(主要組分三硫化二銻)、銻硫鎳礦(硫化銻鎳)和重金屬銻化物。將銻礦石焙燒成氧化物，再用鐵或碳還原可得金屬銻，并經(jīng)電解精制。在半導體工業(yè)中用于制造二極管，紅外檢測器、合金增硬劑、抗摩擦合金、鉛字合金、蓄電池等。銻的氧化物、硫化物和銻酸鈉、用于制造阻燃劑、涂料、陶器釉質，玻璃和瓷器等。金屬銻性狀：有金屬變體和黃色變體兩種同素異形體，前者有銀白色金屬光澤，具有鮮明的晶體結構。溶解情況：不溶于水、鹽酸和堿溶液。武漢5N5銻?；厥?/p><p
