Abstract
The present application relates to C084B, more particularly, the present application relates to a kind of YBCO multilayer thick film preparation method.It includes semi-grown film preparation: YBCO colloid is applied to texture base, obtain colloid film, after low-temperature treatment and high-temperature pretreatment in turn, obtain semi-grown film.The method provided by the present application can overcome thick film effect, can be used for the continuous, large-scale production of YBCO high-performance thick film, promote the more compact structure of multilayer structure YBCO superconducting film formation, and the thickness of thick film can reach 3 μm or more, significantly higher than the thickness of YBCO superconducting film obtained by the same method at present, while the Ic of 12mm width can reach 1000A or more, and the critical current density can reach 2.8MA / cm 2 The above.
