| titleOfInvention | Preparation method of high temperature superconductive film adopting modified low fluoride solution method |
| abstract | The invention discloses a preparation method of a high temperature superconductive film adopting a modified low fluoride solution method, which comprises the following steps: dissolving yttrium oxide, barium acetate and copper acetate as raw materials in a solvent using a complexing agent to obtain a low fluoride yttrium barium copper oxygen solution, preparing a gel film and drying, and performing pretreatment and end treatment of the film. The sol has easily adjustable composition, stable performance and good film forming property, the yttrium barium copper oxygen superconductive film can be easily prepared using the sol, and the heat treatment cycle is short and the process repeatability is high. In addition, the solution avoids the introduction of amine group, so as not only to avoid the loss of copper in the heat treatment, but also to avoid the problem that the film is easy to craze. The method of the invention is also used for preparing large-area or long-distance yttrium barium copper oxygen films and coated conductors, the obtained yttrium barium copper oxygen film has good surface smoothness and has good superconductivity. |
