Advances towards the rolling processing of long BSCCO tapes

Uniform long length Ag clad mono-filamentary BSCCO tapes have been produced by the powder in tube method making use of drawing, cold rolling and annealing processes. The influence of the starting BSCCO powders, packing method and Ag addition on BSCCO/Ag superconducting tapes have been analyzed using XRD and scanning electron microscopy combined with EDX and Image Analysis. In addition, extensive electrical transport measurements have been carried out. Average values of J/sub c//spl ap/12 kA/cm/sup 2/ with a dispersion of /spl plusmn/5% over a 1 m length have been obtained.
