A MAFACTURING METHOD OF PRECURSOR SOLUTION WITH IMPROVED VISCOSITY |
摘要 |
A method for preparing a precursor solution having improved viscosity property is provided to allow preparation of a precursor film, and to improve the critical current characteristics of a superconductive wire material obtained through an organic deposition process. A method for preparing a precursor solution having improved viscosity property comprises the steps of: dissolving acetate salts of yttrium and copper, barium trifluoroacetate and additives into a solvent; and adding a metal carboxylate to the solution formed in the preceding step. The metal ion concentration in the precursor solution is 1-3M. The metal carboxylate includes a rare earth metal acetate or transition metal acetate.
