| 简介 |
PURPOSE : 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.
CONSTITUTION : 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.
