Single crystalline Bi-based superconducting whiskers have been fabricated from a melt quenched Bi 2 SbSr 2 Ca 2 Cu 3 O x precursor using suitable heat treatment cycles. Whiskers fabricated in this study have 6–15 μm thickness, 60–95 μm width and 1–3 mm length. Crystallization activation energy of the material fabricated was calculated to be 609 kJmol −1...
