摘　　要：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 of Bi(2223)/Ag superconduction powders was studied.The results show that,When the process of pressing sintering(800C/24h) griding was repeated three times,homogeneous superconducting powders are acquared its compostion is mainly of 2212 phase with few nonsuperconduction phase and its morphology is mainly granular.
