The research in this paper was conduced with the purpose of developing a electrophoretic deposition process technology, and finding out an optimization method for fabrication of YBCO superconductor thick film tapes by using superconducting YBCO powder, and applying the electrophoresis technique. Through the development of an electrodeposition process, this study tried to determine an optimization method to improve the density and orientation of powder particles and a way to obtain a uniform surface to overcome cracking and porosity problems possibly occurring in the drying and heat-treatment processes. In this study, the electrophoretic deposition technique, which is to align and maintain particles toward the backside of the axis of Ag substrates in a tape form, through excitation of powder particles with AC electric current, and then to perform deposition under a condition, was applied to the electrophoretic deposition process.
