摘要

由于MgB2的临界温度(39k)是超导体中最高的，而且与高温超导体相比，MgB2的化学成分和晶体结构都非常简单，因此受到了世界各国的广泛关注。本文对自传播高温合成MgB2超导体进行了简要的研究。研究了SHS的样品制备、点火方式、结构与磁性能的关系。该方法在MgB2超导体的合成中取得了显著的成功，在超导基体中引入钉钉中心是提高超导性能的实践。

Self-Propagating High-Temperature Synthesis of MgB2 superconductor: A Review

Since the critical temperature of MgB₂ (39 K) is the highest in the superconductors and the chemical composition and crystal structure are very simple as compared to high temperature superconductors, MgB₂ has attracted a lot of attention in the world. This paper is a brief study of self-propagating high-temperature synthesis of MgB₂ superconductor. Sample preparation, ignition mode, and relationship between structure and magnetic properties of finals SHS products were identified. This method has demonstrated significant success in the synthesis of MgB₂ superconductor and the introduction of pinning centers into the superconducting matrix is practice to improve superconducting properties.

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
