锂在工业上是最重要的稀有碱金属,它在金属中的比重最轻,添加在其他金属中形成合金,使合金机械强度提高,所以金属锂及其化合物具有许多特殊的物化性质,这促使锂在生产及其应用方面取得很大进展。特别是在原子能、冶金、电子、玻璃陶瓷、化工、电池和飞机制造等许多领 Lithium is the industrially most important rare alkali metal, which has the lightest proportion in the metal. It is added to other metals to form an alloy to increase the mechanical strength of the alloy. Therefore, lithium metal and its compounds have many special physical and chemical properties that promote Lithium has made great strides in production and its applications. Especially in many fields such as atomic energy, metallurgy, electronics, glass ceramics, chemicals, batteries and aircraft manufacturing
