The metal organic deposition (MOD) method which uses solution materials including trifluoroacetates (TFA) as a solute, is one of the most promising methods to fabricate high-quality superconducting wires at low coast. In this study, a new combination of starting materials was developed using F-free salt of Cu and TFA salts of Y and Ba in order to shorten annealing time. Moreover, a new process temperature profile for this solution was developed as an advanced TFA-MOD process, in which a high heating rate was achieved. As a result, an overall transport
Ic value of 210 A and a
Jc value of 1.5 MA/cm
2 at 77 K in a self-field similar to
Ic and
Jc values using TFA for all salts were obtained. In order to obtain higher
Jc performance, the effect parameters such as partial pressure of the water vapor in the annealing process were investigated. Consequently, a YBCO film of 1.3 μm in thickness was fabricated on a CeO
2/IBAD-Gd
2Zr
2O
7 layer buffered Hastelloy substrate with Δφ =4°. Consequently, the
Ic values increased as the water vapor pressure increased during the crystallization, and the overall transport
Ic value of 340 A at 77 K in a self-field was obtained by annealing under a partial water vapor pressure of 6.3 vol%.
