Preparation of Bi based Superconducting Powders with High Quality
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.
