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。Abstract: 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.
