Abstract:The commercial manufacturing technology of BSCCO high temperature superconducting(HTS) tapes was introduced, with emphases on synthesis and pre-treatment of the precursor, mechanical deformation and thermo-mechanical treatment. Comparison were made on the development status of several companies over the world. In order to meet the requirements of special application such as HTS transmission cable, HTS magnet and current leads, tremendous research efforts was made not only in enhancing the performance uniformity along the whole length of the BSCCO tapes, but also in carrying out diversified tape-design to improve their application properties, which include reducing AC losses and thermal conductivity, increasing insulation properties and so on. Several research directions were put forward, based on improving the performance and lowering the manufacturing cost of BSCCO tapes.
