Effect of suspension parameters towards the fabrication of BSCCO films by electrophoretic deposition

Abstract Superconductor Bi-Sr-Ca-Cu-O (BSCCO) thin films were fabricated on silver by electrophoretic deposition (EPD) method. By investigating the effects of solvents and I 2 additives properties suspension prepared BSCCO powder, particle charging mechanism is analyzed. Studying effect different structure isopropanol best dispersion solvent. Through optimization concentration, results show that optimal concentration 0.08 mg ml −1 . The processing parameters critically influencing morphology are identified optimized to obtain uniform with high packing density particles. After heated at 820 °C for 20 h, smoothest surface morphology, c -axis orientation, highest critical temperature( Tc ) 82 K obtained from film suspension.
