摘要
我们采用多次研磨-烧结工艺制备了直径φ=45mm,厚度t=4mm的铋系2223相超导块材。多次研磨——烧结有利于改善材料的均匀性,提高致密性,增加2223相的生成量。
The preparation technology of lump sample of the Bi-based high-Tc phase has been investigated. It was found that grinding and sintering for many times can help improve the homogeneity and inerease the relative amount of high-Tc phase in samples.
