A Study on Bubbling Control of Bi-2223/Ag HTS tapes
Bi-2223/Ag 고온초전도 선재의 bubbling 제어에 관한 연구
Abstract
Bi-2223/Ag HTS tapes fabricated by PIT process are used to make the power transmission cable, motor, fault current limiter, transformer etc. But some problems are still remained as like bubbling, sausaging to got the high Jc. In this study. we carried out the experiment to prevent bubbling in the HTS tape. The bubbling mainly occurred when HTS tape was heat-treating. Therefore, additional vacuum annealing at 400 ~
