摘要
超导材料因具有超强导电能力、完全抗磁性和约瑟夫森效应,在电力、磁场、超算等领域展现出巨大的潜力。Bi系高温超导材料的临界使用温度高于液氮的沸点(77K),能够制成带材和线材,且可承载的电流大,被认为是一种非常具有前景的实用化超导材料。本文主要介绍了Bi系高温超导材料的结构和主要的制备工艺,从制备前驱粉末的三种主要工艺方面,介绍了国内开展的相关研究,简要分析了这三种制备工艺的优缺点。
Superconducting materials exhibit great potential in the fields of electricity,magnetic fields,and supercomputers due to their superior electrical conductivity,complete diamagnetism and Josephson effect. Bi-based high-temperature superconducting materials can achieve a critical use temperature higher than the liquid nitrogen boiling point of 77 K,can be made into strips and wires,and can carry a large current,is considered to be a very promising practical superconducting material. This paper mainly introduces the structure and main preparation process of Bi-based high-temperature superconducting materials. From the three main processes of preparing precursor powders,the related researches carried out in China are introduced,and the advantages and disadvantages of these preparation processes are briefly analyzed.
