(Summary description)　　At the "High Temperature and High Field Superconducting Material and Its Application Technology Seminar" held on April 28, industry experts discussed the promotion of technological upgrading and progress in the field of domestic superconducting materials. At present, the development of superconducting materials has been written into "Made in China 2025" and is expected to be included in the "13th Five-Year Plan" for the new material industry. In this regard, industry insiders said that with the country’s attention and the promotion of production, education and research, the industrialization of high-temperature superconducting materials is about to break.

　　When the temperature drops sufficiently low (ie, the critical temperature), the resistance of some materials becomes zero, which is called superconductivity. The use of superconductors can minimize transmission losses and reduce mechanical wear. High-temperature superconducting materials have outstanding and irreplaceable roles in many fields such as electric power, communications, high-tech equipment, and military due to their "high critical transition temperature and ability to work under liquid nitrogen temperature" characteristics.

　　Based on the huge market prospects and a high degree of strategy, high-temperature superconducting technology and industrialization have become the strategic focus of international competition, and are highly valued by major developed countries such as the United States, Japan, and Germany. Among them, Japan has formulated a national-level superconducting strategic technology roadmap, and South Korea has proposed to lay 50 kilometers of high-temperature superconducting cables in the next five years. Data show that international high-temperature superconducting materials have transitioned to the second generation, and the United States and Japan are leading the way in industrialization. American Superconducting Corporation and Super Energy Corporation realized the industrialization of second-generation superconducting materials and monopolized the market for a long time around 2002; around 2012, a number of second-generation high-temperature superconducting materials emerged in Japan, South Korea, and Germany. Supplier.

　　According to experts, my country is at the world's advanced level in the R&D and industrialization of high-temperature superconducting materials, and its industrialization prospects are huge. At present, there is a need for superconductivity in the fields of electric power, communications, national defense and medical treatment. Only the CEPC (Circular Electron Positron Collider)-SPPC (Super Proton Collider) project led by the Institute of High Energy Physics of the Chinese Academy of Sciences requires about 10 Ten thousand kilometers of high-temperature superconducting materials, even taking into account the substantial decline in future prices, will still bring more than tens of billions of dollars in the strip market.

　　In the industrialization of high-temperature superconducting materials, a number of domestic companies have taken the lead. According to experts, the main domestic companies engaged in the development of second-generation high-temperature superconducting strips are Shanghai Superconducting Technology Stock Co., Ltd. (hereinafter referred to as "Shanghai Superconducting"), Shanghai Shangchuang Superconducting Technology Co., Ltd. and Yongding Co., Ltd. Suzhou New Materials Research Institute Co., Ltd., etc. Among them, Shanghai Superconducting and Shanghai Jiaotong University jointly established the "Shanghai Superconducting Joint Research Institute", which took the lead in realizing the mass production and sales of domestic materials in 2014. Its customers include scientific research institutes such as the Chinese Academy of Sciences and companies in the electric power and military industries. The market share exceeds 70%; at the same time, it is also the world's first company capable of providing production equipment. Suzhou New Materials Research Institute Co., Ltd. has also established a second-generation high-temperature superconducting tape production line at the kilometer level, and the products have been tried out in the fields of military industry and electric power.

　　Industry insiders said that with the country’s attention and the promotion of production, education and research, the industrialization of high-temperature superconducting materials is about to break. At present, the development of superconducting materials has been written into "Made in China 2025" and is expected to be included in the "13th Five-Year Plan" for the new material industry. At this seminar, experts agreed that a complete superconducting technology team should be formed to accelerate technology and industrialization research, and expect to achieve major disruptive breakthroughs within 5 to 10 years to promote technological upgrading and progress in related domestic industries.
