Abstract

Bi2Sr2CaCu208,6 (Bi-2212) films were fabricated using sedimentation deposition technique. Bi-2212 was synthesized using solid state sintering. The powder mixed with acetone to produce a suspension. The suspended powder was then deposited onto the surface of the MgO substrate to produce a Bi-2212 film. The prepared films were subjected to heat treatment with a temperature profile especially designed for Bi-2212 film growth. The annealing segment of the temperature profile was varied. Samples were annealed for 10 hours, 15 hours and 20 hours, respectively. The quality of the films was analyzed using the SEM and XRD. It was shown that the 10-hour annealing time favored a c-axis oriented Bi-2212 film.
