前言钪属典型的稀散元素,在矿石中含量很低。而且极其分散,一般从矿石中直接分离、提纯钪的工艺十分复杂,致使钪的价格相当昂贵。但由于钪具有许多优良的性能,近年来国内外对钪在宇航材料、电子工业、超导技术、光源和医药等方面运用研究已受到普遍的重视,并随着科学技术的发展,实现对钪有效地经济地提取,必将使钪在一些潜在地领域里得到广泛地应用。
Preface Scandium is a typical rare earth element that is low in ores. And extremely dispersed, the general separation directly from the ore, scandium purification process is very complicated, resulting in the price of scandium is quite expensive. However, scandium has many excellent properties. In recent years, researches on scandium application in aerospace materials, electronics industry, superconducting technology, light source and medicine have received universal attention. With the development of science and technology, scandium The efficient and economical extraction of scandium is bound to make it widely used in some potential areas.
