摘 要: 通常情况下，单质铝很难与水发生化学反应，利用专利技术可 以用单质铝与纯水进行水解反应制备高纯氧化铝。文中肯定了单质铝具 有较高的化学活性，对铝发生钝化的原因进行了解释；用液态金属的准 晶体理论对急冷工艺活化后铝单质具有极高化学活性的原因进行了分析， 从内外因两个方面对单质铝能够与水发生水解反应的机制进行阐释。

Abstract: Aluminum usually doesn’t react with water. However, the patent technique can make aluminum react with water to prepare high-purity alumina powder. The principle of the patent technique are explained from two aspects. Aluminum has high activity,and the factors why passivation occur to aluminum are explained. The reasons why the activated aluminum has high chemical activity are analysed through the quasi-crystal theory of the liquid metal.
