MgB2超导纳米结构的制备技术

摘要

系统综述了MgB2超导纳米结构的制备方法,包括基于广义模板法的两步法或多步法、反应烧结法、基于电子束刻蚀技术、高温直接分解法、溶胶-凝胶法和混合物理化学气相沉积法等.总结了MgB2超导纳米结构的生长机理,并且评价了这些方法的优缺点.%The preparation technology of MgB2 nanostructure is reviewed. The production methods of MgB2 nanostructure, such as general template-based two-steps or multi-steps, reactive sintering, electron beam lithographybased technique, direct pyrolysis method, Sol-Gel synthesis, combination of physical and chemical vapor deposition respectively are systematically introduced. The growth mechanisms and the problems involved in the existing synthesis methods are summarized. Characteristics of the above methods are also reviewed.
