摘要
以钇钡铜氧化合物为代表的第二代高温超导材料具有高临界磁场、高临界温度、高电流密度等本征物理优势。第二代高温超导材料的超导电性自被发现以来,便受到了世界范围内的广泛关注。近年来涂层导体长带的研制在日本和美国等国家取得了巨大进展,目前主要的技术路线为离子束辅助沉积(IBAD)和轧制辅助双轴织构基带(RABiTS)2种,其中IBAD技术路线的使用更为广泛而且产品性能处于领先地位。随着超导带材制备工艺的逐步成熟和应用技术的不断探索,二代高温超导材料在各行业中的应用正由实验室走向实际应用。
With the high upper critical magnetic field,high operating temperature and high critical current density,the seccond-generation high-temperature superconducting matreials repereented by Yttrium-Barium-Copper-Oxide have drawn worldwide attention since they were discovered in the last century.Therefore,lots of efforts have been made to develop coated conductors all over the world,especially the tremendous progresses made by Japan,USA and other countries for fabrication of coated conductor long tapes in recent years.There are two main technical routes to fabricate coated conductors,which are Ion Beam Assisted Deposition(IBAD)and Rolling Assisted Biaxial Textured Substrates(RABiTS).IBAD was utilized more widely and has achieved better product performance.With the gradual maturity of superconduting strip fabrication technology and the continuous exploration of application technology,the application of seccond-generation high-temperature superconducting matreials in various industries is moving from laboratory to practical application.
