大家知道,纯铝不溶于水,因为铝的表面形成了一种薄而坚硬类似盾甲的氧化物,使金属不能与氧进行接触。但是,任何坚硬的盾甲也能找到对付它的矛。苏联哈萨克苏维埃社会主义共和国科学院有机催化及电化学研究所的科学家们研制出一种新的铝合金。由于在铝合金中添加了镓、铟和锡,它不但不形成氧化膜,还能积极地与水相互作用,并溶于水。反应过程很有意思。反应中水析出大量的氢:每1克铝能使水析出1升多的气体。可贵的是,铝合金的溶解速度可以控制,因而可以改变氢的析出量。苏联科学家的工作成果究竟有甚么用处呢?我们
As we all know, pure aluminum is not soluble in water, because the aluminum surface forms a thin and hard shield-like oxide, so that the metal can not contact with oxygen. However, any hard shield can also find a spear to deal with it. Scientists at the Institute of Organic Catalysis and Electrochemistry at the Soviet Academy of Sciences in the Soviet Union of the Soviet Socialist Republic of Kazakhstan have developed a new type of aluminum alloy. Due to the addition of gallium, indium and tin to aluminum alloys, it not only does not form an oxide film, but also actively interacts with water and dissolves in water. The reaction process is very interesting. Large amounts of hydrogen are liberated from the reaction: 1 liter of gas is precipitated per 1 g of aluminum. Valuable that aluminum alloy dissolution rate can be controlled, which can change the amount of hydrogen precipitation. What is the use of the achievements of Soviet scientists?
