Abstract

Transmission electron microscopy and energy dispersive X-ray spectroscopy were utilized to investigate the composition and microstructure of Pb-doped (Bi-2223)/Ag composite conductors. The observed differences are discussed with respect to the measured electric properties. Detailed TEM observations revealed a brick-wall microstructure, which is also characteristic of high quality powder-in-tube processed Bi-based superconductors. However, the specimen prepared from the precursor having the smallest y value (y = 0 and 0.4 moles of Ca₂PbO₄) contained a large number of Bi-2223 grains with small aspect ratio. The presence of these grains probably caused the formation of weakly coupled grain boundaries and hence lower critical current densities.
