Superconducting material is a typical quantum material that features unique zero-resistance and Meissner effects. With the introduction of superconducting materials, numerous disruptive technologies in electric power applications, such as ultra-strong magnetic fields and large-capacity power transmission, can be realized, which makes the fabrication technique of large-current-capacity superconducting materials the frontier field worldwide. This study summarizes the development status of superconducting materials for electric power application as well as their fabrication techniques, and clarifies the development trends of several practical superconducting materials, including low-temperature superconducting materials (e. g., NbTi and Nb3Sn) and high-temperature superconducting materials (e.g., YBCO coated conductors, Bi-2223 tapes, Bi-2212 wires, and MgB2 wires). Considering the problems existing in the development of the superconducting materials for electric power application in China, it is imperative to establish a high-performance superconducting material system that satisfies varied electric power application requirements to achieve the integrated development of superconducting materials and electric power application products and to promote the innovation and industrial scale of these materials and applications. Furthermore, we suggest that the integrated development of production, education, research, and application should be promoted in the national level to upgrade the low-temperature superconducting material industry and achieve breakthroughs in batch production of high-temperature superconducting materials, thereby realizing the rapid development of superconducting materials for electric power application.

Low temperature hydrogenation catalyst CT6-11 has been used in tail gas treatment unit of sulfur recovery plant with 4 000 t/a of Dushanzi Petrochemical Company since August 2011. The result of running for one year shows that CT6-11 has a good low temperature hydrogenation and hydrolysis performance. Hydrogenation conversion of SO2 can reach 100%, and COS hydrolysis is over 99%. [ABSTRACT FROM AUTHOR]

As a functional material of burn-resistant titanium alloy, the physical properties of Ti40 alloy were first reported. The chemical compositions of Ti40 alloy ingots by VAR were uniform. The microstructures of Ti40 alloy slab manufactured by HEFF+WPF were uniform. The results show that the room temperature tensile strength of Ti40 alloy is 950 MPa degree. The properties of high temperature heat exposure, creep resistance and lasting time are good at 500 ℃. In the range from room temperature to 600 ℃, Young's modulus and shear modulus are decreased linearly with increasing the temperature, Poisson's ratio is increases slowly as the temperature rises, and linear thermal expansion coefficient and average linear expansion coefficient is increase as the temperature rises.
