目前，已制备出77K下的多芯Bi2223/Ag带材，是制备高温超导(HTS)电力导体的最佳候选材料。本文介绍并讨论了管内粉末法制备长Bi2223/Ag带材的工艺过程，考察了所选工艺参数对最终导体性能的影响。讨论了高温超导的局限性，并简要介绍了Bi2223/Ag或Bi2212/Ag带材的一些可能的应用。
At present, rolled multifilamentary Bi-2223/Ag tapes exhibiting at 77 K are fabricated, making them the most favourable candidates for the fabrication of high-temperature superconductor (HTS) conductors for power applications. In this paper the fabrication process of long Bi-2223/Ag tapes by the powder-in-tube technique is presented and discussed with the aim of surveying the influence of some selected process parameters on the properties of final conductors. limitations in HTSs are discussed and some of the possible applications of Bi-2223/Ag or Bi-2212/Ag tapes are briefly presented.
