Abstract
Bi2Sr2Ca1Cu2Ox (BSCCO-2212) tubes were fabricated by melt and solidification process. BSCCO-2212 powder compact was melted in a resistance furnace using a Pt crucible and poured in a rotating cylindrical mold. The solidified BSCCO-2212 tube samples were heat-treated at various temperatures in oxygen atmosphere. The current–voltage curves at 77K of the samples were obtained by transport measurement, and the microstructure was investigated by scanning electron microscope. It was found that the critical current (Ic) of the BSCCO-2212 samples was dependent on the heating schedule regarding the grain growth of the BSCCO-2212 plates and the formation of the second phase.
