SmBiO_3 Buffer Layer of Superconducting Coated Conductor Prepared on NiO/NiW by Fluorine-free Chemical Method

在能源日趋紧缺的形势下,高温超导材料的应用具有可观的前景。经济、高效、节能的REBCO超导涂层导体的制备技术成为其大规模应用的关键,目前,非真空的化学溶液沉积技术是降低涂层导体制备成本的重要途径。于空气条件下制备了NiO薄膜,并在NiO薄膜上使用无氟化学方法制备了SmBiO3薄膜,作为REBCO超导涂层导体的缓冲层。研究了NiO薄膜质量对制备SmBiO3薄膜的影响,旨在为REBa2Cu3O7-δ涂层导体的制备提供一条非真空全化学法的途径。

With energy shortage becoming increasingly severe, the application of high-temperature supercon ducting material is considerable prospects. Economic, efficient, energy-saving preparation techniques become the key for the large-scale applications of REBCO superconducting coated conductors. Currently, non-vacuum chemical solu- tion deposition technique is an important way to reduce the cost of preparation of coated conductors. The layer of SmBiO3 was fabricated on NiO film in air via a fluorine-free chemistry method. This composite SmBiO3/NiO layers are used as buffer layers of REBCO superconducting coated conductors. The effects of the NiO films quality on SmBiO3 films are studied. The purpose of this paper is to provide a potential value of non-vacuum chemical solution deposition technique for preparation of REBCO superconducting coated conductors.
