什么是铝
铝的由来
是谁发明的
有什么用处
就是一篇简单英文的介绍

Silver white light metal. Has the ductility and malleability. Products are made of rod-like, sheet, foil, powder, ribbon and filamentous. In the humid air can form a layer of oxide film to prevent metal corrosion. Aluminum and aluminum foil in air heated to burn fiercely, and emits a blinding white flame. Easy to dissolve in the dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, do not dissolve in water. The relative density of 2.70. The melting point of 660 DEG c.. The boiling point of 2327 DEG c.. Aluminum content in the crust comes next only to oxygen and silicon, and ranks the third in the earth's crust, is the most abundant metal element. Aviation, construction, automotive three major industrial development, requirements of material characteristics of aluminum and its alloy unique properties, which greatly facilitates the new metal aluminum production and application. The application is very extensive.In 1854, the French chemist Deweier bauxite, charcoal, salt to the mix, the chlorine gas and heated to NaCl, AlCl? And then the compound salt and salt, sodium melting, obtained by metal aluminum.
银白色轻金属.有延性和展性.商品常制成棒状、片状、箔状、粉状、带状和丝状.在潮湿空气中能形成一层防止金属腐蚀的氧化膜.铝粉和铝箔在空气中加热能猛烈燃烧,并发出眩目的白色火焰.易溶于稀硫酸、硝酸、盐酸、氢氧化钠和氢氧化钾溶液,不溶于水.相对密度2.70.熔点660℃.沸点2327℃.铝元素在地壳中的含量仅次于氧和硅,居第三位,是地壳中含量最丰富的金属元素.航空、建筑、汽车三大重要工业的发展,要求材料特性具有铝及其合金的独特性质,这就大大有利于这种新金属铝的生产和应用. 应用极为广泛.
1854年,法国化学家德维尔把铝矾土、木炭、食盐混合,通入氯气后加热得到NaCl,AlCl?复盐,再将此复盐与过量的钠熔融,得到了金属铝.
