摘要
阐述了过渡金属铬在现代高科技工业、国防与尖端技术领域中的重要地位,其应用范围也越来越广泛。文章综述了铬资源的储量及其在世界范围内的分布态势和我国铬资源特点,铬及其化合物在现代科技领域中的主要用途;重点介绍了目前已经比较成熟的有关铬的提取分离技术以及一些近年发展起来的尚处于实验研究阶段的新技术,展望了未来单质铬提取分离技术的发展方向。
Owing to its important position in modem high-tech industry,national defense and cutting-edge technologies,the transition metal chrome has always been the people＇s attention and the range of its applications is increasingly wide.In this paper,chrome reserves and its distribution in the world,features of Chinese chrome resources and the main uses of chrome and its compounds in modern science and technology field are summarized.The mature technologies of extraction and separation of chrome as well as some recent new technologies which is still in the experimental stage are mainly introduced and look into the distance for the future development direction of chrome extraction and separation technology.
