Advances towards the rolling processing of long BSCCO tapes

A powder-in-tube technique using cold rolling, drawing and annealing processes was utilized in fabricating uniform long length silver-clad monofilamentary BSCCO tapes. EDX, XRD, image analysis and scanning electron microscopy were employed in analyzing the effects of the starting BSCCO powders, the packing technique and the Ag addition. Electrical transport measurements reveal average values of Jc=12 kA/cm2 with a dispersion of +/-5% over a 1 m length.
