我国是世界最大的稀土金属及合金生产国和供应国,但在超高纯稀土金属制备技术方面却相对落后。为此“十二五”期间,863计划在新材料技术领域设立了“超高纯稀土金属及合金节能环保制备技术”课题,由北京有色金属研究总院牵头承担。经过几年攻关,课题取得了一系列重大进展,并于2014年6月下旬顺利通过了科技部组织的专家验收。课题组通过稀土金属制备、提纯技术及装备的集成创新,突破超高纯稀土金属制备关键技术,自主设计研制了超高真空蒸馏炉、
China is the world’s largest producer and supplier of rare earth metals and alloys, but it lags behind in the preparation of ultra-high purity rare earth metals. To this end, during the “12th Five-Year Plan” period, the 863 Program has set a new topic in the field of new material technologies, which is led by Beijing Nonferrous Metal Research Institute. After several years of research, the subject made a series of significant progress and passed the acceptance of experts organized by the Ministry of Science and Technology in late June 2014. The research group through the rare earth metal preparation, purification technology and equipment integration innovation, breakthrough in ultra-high purity rare earth metal preparation of key technologies, independent design and development of ultra-high vacuum distillation furnace,
