Abstract

Bi2Sr2CaCu2O8 (Bi-2212) superconducting tape was fabricated using calendering method. This novel technique of producing Bi-2212 tape uses aluminum as cladding material, where Bi-2212 powder is subjected to rolling and annealing to promote alignment of grains. The powder was produced using solid-state reaction method. X-ray diffraction verified the existence of Bi-2212 while the superconducting property was determined using magnetic susceptibility. The graph of magnetic susceptibility versus temperature showed that the T, of the samples is approximately 77 K. The microstructure of the tape was observed under Scanning Electron Microscopy (SEM). Results showed that the sample annealed at 600°C attained more homogeneous surface and lesser porosity than the sample annealed at 550°C.
