摘要

用R2O3(R分别为Gd,Y和Yb),BaCuO2和CuO配制了三种新成分液相源.利用顶部籽晶熔渗生长工艺,分别用这三种新成分液相源制备了单畴Gd-Ba-Cu-O超导块材,并对所得样品的生长特性和微观结构进行了研究.结果表明,使用新液相源可以缩短实验周期,提高制备效率,并能获得织构度良好的单畴块材.此外,由Y2O3或Yb2O3

Three new kinds of liquid source were prepared by mixing R2O3 (here R is Gd,Y or Yb respectively),BaCuO2 and CuO powders. Single-domain Gd-Ba-Cu-O bulk superconductors have been fabricated using these liquid sources by the top seeded infiltration and growth technique. The growth characteristic and microstructure of the samples have also been investigated in detail. The results indicate that, employment of the new liquid sources not only can help us reduce the experimental period and improve the fabrication efficiency, but also can be used to fabricate well-textured single domains. Additionally, using the liquid source mixed by Y2O3 or Yb2O3 can raise the utilization rate of the liquid source powders, as well as contribute to the refinement of Gd-211 particles in the molten liquid.
