摘要：

A novel liquid wicking process has been developed to produce silver-sheathed Bi-2212 samples with oxide core thicknesses of 10-20 mu m, uniform oxide/silver interfaces, small non-superconducting phases and low porosity. This technique avoids many problems associated with oxide-powder-in-tube (OPIT) processing by exploiting the wicking behavior exhibited by Bi-Sr-Ca-Cu-O (BSCCO) liquid between silver surfaces. Critical current densities over 50000 A/cm(2) at 4 K in self-field have been achieved with an isothermal melt process and Bi2.1Sr2Ca0.9Cu2Ox composition powder.
