摘　　要：钪是一种稀散型元素,在自然界大多以掺杂的形式存在于其它矿物中。概括了稀土元素钪的性质与资源,同时论述了钪的提取现状以及如何制备高纯金属钪,并且介绍了钪在铝合金和阴极材料方面的应用,最后展望了钪的发展。Scandium is a kind of sparsity and spread around element. In the nature, it mostly exists in other minerals in the form of intermingle. This text briefly discussed the origins and characteristics of scandium. Then it introduces the research state of extraction of scandium and how to prepare the high pure scandium. Next it introduces the application of scandium in aluminum-alloys and cathode materials. At last it gives a conclusion of the prospect of scandiurn.
