Method of producing a superconducting Bi-based oxide wire. |
摘要 |
<p>In order to obtain a Bi-Sr-Ca-Cu-O or Bi-Pb-Sr-Ca-Cu-O oxide superconducting wire, raw material powder is pulverized to remove particles of non-superconducting phases having large particle sizes based on difference in particle size, and thereafter the raw material powder is covered with a sheath of silver or silver alloy, so that the sheath is subjected to plastic working and the raw material powder covered with the sheath is sintered.</p> |
