航空、建筑、汽車三大重要工業(yè)的發(fā)展，要求材料特性具有鋁及其合金的獨特性質(zhì)，這就大有利于這種新金屬鋁的生產(chǎn)和應(yīng)用。應(yīng)用極為廣。銻和鋁的區(qū)別bai：鋁銀du白色輕金屬。zhi有延展性。銻帶dao有銀色光澤的灰色金屬。鋁易溶于稀zhuan硫酸、硝酸、鹽酸、氫氧化鈉和氫氧化鉀溶液，難溶于水。銻易溶于王水，溶于濃硫酸。鋁的英文名出自明礬，即硫酸復(fù)鹽KAl(SO4)2·12H2O。史前時代，人類已經(jīng)使用含鋁化合物的黏土（Al2O3·2SiO2·2H2O）制成陶器。銻是一種有毒的化學(xué)元素，元素符號為Sb，原子序數(shù)為51。它是一種有金屬光澤的類金屬，在自然界中主要存在于硫化物礦物輝銻礦（Sb2S3）中。目前已知銻化合物在古代就用作化妝品。鋁在潮濕空氣中能形成一層防止金屬腐蝕的氧化膜。鋁粉在空氣中加熱能猛烈燃燒，并發(fā)出眩目的白色火焰。銻在潮濕空氣中逐漸失去光澤，杭州5N銻丸，強熱則燃燒成白色銻的氧化物。鋁有24種同位素，其中只有一種是穩(wěn)定的。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，其中半衰期很長的Sb為。鋁的密度很小，杭州5N銻丸，只為g/cm，銻的密度達到，但層與層之間的成鍵很弱也造成它很軟且易碎。銀白色有光澤硬而脆的金屬。銻是氮族元素（15族），電負性為2，杭州5N銻丸.05。根據(jù)元素周期律，它的電負性比錫和鉍大，比碲和砷小。杭州5N銻丸</p><div

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，近而染上肺不死。雖然至今尚未出現(xiàn)因吸入過量銻而染上肺不死的個案，但仍不排除其對人體的潛在危險。2002年9月，世界衛(wèi)生組織規(guī)定，對水中銻含量和日攝入量應(yīng)小于。日本限定寶特瓶中的銻含量應(yīng)小于200ppm，對熱灌裝用的飲料，則禁用含銻的寶特瓶。歐盟則規(guī)定，食品中的銻含量應(yīng)小于20ppb，環(huán)保級PET纖維中的銻含量不得大于260ppm。注意事項：風(fēng)險危害：1.吸入及吞食有害。2.對水生生物有毒，可能對水體環(huán)境產(chǎn)生長期不良影響?！句R的危害】對常見的12個品牌的飲品和調(diào)味品的塑料瓶體進行了檢測，發(fā)現(xiàn)采用PET材料制成的瓶體均含有致不死物-重金屬銻。銻會刺激人的眼、鼻、喉嚨和皮膚，持續(xù)接觸可破壞心臟及肝臟功能，吸入高含量銻會導(dǎo)致銻中毒，癥狀包括嘔吐及頭部不適、呼吸困難，嚴(yán)重者可能死亡。塑料包裝：塑料在我們的生活中無處不在，而關(guān)于塑料有害身體的傳言也從未中斷。PET是目前飲品使用很多的包材。搜狐健康對常見的12個品牌的飲品和調(diào)味品的塑料瓶體進行了檢測，發(fā)現(xiàn)采用PET材料制成的瓶體均含有致不死物——重金屬銻，在本次檢測中，9個PET材料的塑料瓶均檢出銻。綿陽銻粒這種距離上的相對近使得金屬銻的密度達到6.697

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。[13]銻其他應(yīng)用其他的銻幾乎都用在下文所述的三個方面。較好項應(yīng)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(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；這是因為銻離子與氧氣接觸后阻礙了氣泡繼續(xù)生成。第三項應(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(diào)節(jié)劑。銻對角質(zhì)化的組織有滋養(yǎng)和調(diào)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氖牵恢挥杏弥笖?shù)較低。</p><p>
