Abstract:
The MgB 2 superconductive material was synthesized by means of solid
sintering reaction under the flowing argon atmosphere and in the vacuum sealed
quartz glass tube respectively. The effects of the phase change in Mg-B synthetic
process and the ratio of powder on synthetic samples purity in solid sintering reaction
were investigated in this paper. Besides, the effects of sintering technology on synthetic
process of MgB 2 were also discussed.
分别在流动Ar和真空的密封石英玻璃管条件下制备了MgB 2 超导材料。
研究了固相烧结反应合成 Mg-B 过程中相的变化以及粉末配比对合成样品纯度
的影响,并讨论了烧结工艺对合成 MgB 2 的影响。
