The present study shows general characteristic features of processes such as electrodeposition, drying, and heat-treatment, involved in the preparation of bufferless Tl-1223/Ag superconducting coated conductors by using an electrodeposition method, the details of which have not been reported in the literature. The importance of the present study, however, lies in a new process to make a thick Tl-1223 superconducting layer by using electrodeposition. In the new method, a relatively thin Tl-1223 precursor film is firstly electrodeposited on an Ag sheet, dried, and then heat-treated for phase transformation to superconducting phases to assign conductivity to the film. Then Tl-1223 precursor film is electrodeposited again on the heat-treated superconducting film, dried, and heat-treated. The process of electrodeposition, drying, and heat-treatment can be repeated many times to prepare a very thick superconducting layer. In the present study, a 2–3 µm thick Tl-1223 layer was prepared on a &\{113\}\langle 121\rangle ; intensified Ag sheet by repeating the process once. Even though Jc values in thick Tl-1223/Ag were quite low mainly due to material loss during heat-treatment, the microstructure analysis indicated that Tl-1223 layers were epitaxially grown on the &(113)\langle 121\rangle ; intensified Ag sheets provided that the Ag surfaces were flat and clean.
