研究了Ｂｉ（２２２３）／Ａｇ高温超导带材的装管粉末的制备工艺。结果表明，烧结—压片—研磨的工艺过程重复三次，能得到成分均匀、以２２１２相为主的超导粉末，粉末的形貌以粒状晶粒为主，伴随少量针状晶粒。
The preparation process of tube powder for Bi (2223) / Ag high temperature superconducting tapes was studied. The results show that the sintering process, tabletting and grinding process are repeated three times to obtain a superconducting powder with uniform composition and predominantly 2212 phase. The morphology of the powders is mainly granular grains with a few acicular grains.
