Abstract:

The scientific connotation of rare earth crystals,including the concept,discipline characteristics and classification,was introduced.The current R&D status of rare earth crystal materials,including rare earth magnetic materials,optical mate-rials,electrical materials,catalytic materials,energy materials,alloy materials and rare earth raw materials,was expounded.It was pointed out that China has built an industry system from rare earth raw materials production such as mineral exploration and exploitation,mineral selection,extraction,separation and smelting,to downstream R&D of rare earth structured and functional materials,and has formed the world′s most complete and first-largest rare earth new material industry system.How-ever,the core technology in the field of rare earth high-tech materials and devices has not been systematically mastered.In response to the lack of innovation,the high-value utilization of rare earth resources and other issues,China needs to further strengthen basic scientific research,applied fundamental research,industrial development,resource recovery and so on.

Key words: rare earth crystal, rare earth resource, rare earth functional materials, rare earth industry planning, rare earth high-quality development
