According to the Ministry of Science and Technology's website, under the support of the "Project for New High-temperature Superconducting Materials and Physics" of the 973 Program, the Ma Yanwei Group of the Institute of Electrical Engineering of the Chinese Academy of Sciences adopted the new technology of mechanical pressing and developed the Sr-122 iron-based superconducting tape. This indicates that China's iron-based superconducting materials have entered the threshold of practical application, and laid a solid foundation for the next large-scale preparation of long-term iron-based lines. After developing the world’s first iron-based superconducting wire rod in 2008, the research group continued to improve iron-based superconducting wires by systematically studying metal sheathing materials, mechanical processing and heat treatment processes, doping modification, and texture orientation. The critical current density of the strip. At present, the research group is working hard to realize the multi-core preparation and elongation of this type of superconducting tape, which will lay a solid foundation for realizing the application of iron-based superconducting materials in strong magnetic fields and energy. Analysts pointed out that as early as a few years ago, there were brokerages publishing research reports that the potential size of the superconducting market reached 200 billion yuan, of which the core superconducting materials accounted for 30%-40%, about 80 billion yuan. The current industry chain of the superconducting industry consists of three parts: the upstream mineral resources such as thorium and antimony; the middle reaches are superconducting materials such as YBCO and BSCCO; and the downstream are superconducting applications such as superconducting cables and superconducting current limiting Devices, superconducting filters, superconducting energy storage, superconducting generators, superconducting transformers, etc. The most advanced, most widely used and most commercialized superconducting materials are BSCCO high-temperature superconducting materials. As for the specific stocks that can be watched, currently superconducting has entered the stage of industrialization. The potential market size is 200 billion yuan. The listed companies' superconductivity-related projects are particularly worthy of attention. Related companies include Zhongfu Industry, Zhongtian Technology, Baili Electric, and Baosteel.
