Abstract :
The feasibility of electrophoretically depositing the 2212 phase of BSCCO onto silver substrates has been established. By choosing suitable processing parameters, the resulting thick films have smooth surfaces without cracks and exhibit well-defined superconducting transitions near 80 K. Results on the temperature dependence of the electrical resistance of deposited Bi-Sr-Ca-Cu-O and Bi(Pb)-Sr-Ca-Cu-O films with different sintering conditions are presented
