High-temperature superconducting film material and manufacturing method thereof

Abstract

The invention relates to a high-temperature superconducting film material and a manufacturing method thereof. The high-temperature superconducting film material is prepared from the following ingredients in percentage by mass: 2.2 to 4.0 percent of yttrium trifluoroacetate, 3.0 to 4.0 percent of copper trifluoroacetate, 4.8 to 7.8 percent of barium trifluoroacetate, 2.3 to 3.5 percent of terpilenol, 9.0 to 13.0 percent of titanium acetylacetone, 5.5 to 8.0 percent of zirconium acetylacetone and the balance of niobium. During the preparation, the method comprises the following steps of providing various hydrochloric acid solutions; performing uniform mixing; performing stirring; removing moisture to obtain pure gel; adding terpilenol to prepare precursor liquid; spraying the precursor liquid on a substrate, and performing low-temperature thermal decomposition; after thermal treatment, performing annealing heat treatment. The inventor performs a large number of ingredient and consumptionscreening experiments at the earlier stage, and accidentally finds that the current carrying capacity of the film material is greatly improved; the production cost of a coating conductor is reduced;the application range of the superconducting film material is expanded; wide application prospects are realized.
