日前,在由中国科学技术协会主办、中国稀土学会承办的第三十七次中国科技论坛上,中国工程院院士、中国工程院原副院长、中国稀土学会理事长干勇指出“稀土材料是发展高新技术和国防尖端技术不可缺少的关键原材料,高性能、高纯度和开拓新应用是稀土材料发展趋势。”干勇并指出“我国稀土高端产品严重依赖进口,将来须重点开发高效清洁分离与高纯化制备一体化新技术,规模化生产绝对纯度>4N的超高纯稀土金属、相对纯度>6N的高纯 Recently, at the 37th China Science and Technology Forum hosted by China Association of Science and Technology and hosted by China Rare Earth Society, Qian Yong, academician of the Chinese Academy of Engineering, former vice president of the Chinese Academy of Engineering and chairman of the Chinese Society of Rare Earths, pointed out that ”the development of rare earth materials High-tech and national defense cutting-edge technology indispensable key raw materials, high performance, high purity and open up new applications is the development trend of rare earth materials. “” Dry Yong pointed out that "China’s high-end rare earth products rely heavily on imports, the future must focus on the development of efficient clean separation Preparation and integration of high-purity new technology, large-scale production of absolute purity> 4N of ultra-high purity rare earth metals, the relative purity of> 6N of high purity
