Bi-based mono-core superconductor tapes : fabrication process and the effect of the thermomechanical treatment on the transport properties / K.T. Lau and R-Abd Shukor

Fabrication of the Bi-based tapes started with the preparation of its precursor powder with composition of Bi1.8 Pb 0.4 Sr2 Ca2.2 Cu3 O10+y. The post-annealed powder with a majority of 2212 phase was then ground before it was packed into a silver tube. Then the composite was sway-rolled and drawn in...
