摘　　要：B i-Sr-Ca-Cu-O(BSCCO)高温超导材料在电力工程中拥有广阔的应用前景。本文全面概述了国内外研究B i系高温超导材料连接技术的现状和不足,重点介绍了BSCCO带材常规冷压成形后再高温反应退火的扩散焊连接技术,另外,阐述了近几年采用高温加压直接扩散连接的最新研究成果。Bi-Sr-Ca-Cu-O （BSCCO）high temperature superconductor materials will be extensively used for electrical engineering applications. In this paper, systematic summarizations were made on the bonding technology developments of BSCCO superconductor materials, with emphases on the conventional diffusion bonding of BSCCO tapes through first cold welding and then reaction annealing at high temperature. The disadvantages of the available bonding technologies were appointed out. In addition, the recent achievements with the new technology of direct pressuring diffusion bonding at high temperature were expounded.
