The use of a high-temperature superconductor to manufacture products for commercialization requires a superconductor with a flexible function designed to meet the characteristics of each product. Appropriate mechanical properties need to be maintained to overcome the Lorenz force generated
under high magnetic fields. Several studies focused on the improvement of superconductivity and the development of processing technology. However, high temperature superconductivity wires are not intended for large-scale applications at liquid nitrogen temperature (77 K). Recently, ceramic
superconductors have been fabricated into bulk and thin films or wire rods for electric power applications; however, ceramics are hard to deform due to increased hardness, which is one of the biggest limitations of a superconductor, and a major obstacle to industrial applications. To overcome
these limitations, a synthetic method for superconductivity to reduce the hardness of ceramic superconductor and prevent its degradation was proposed for applications such as superconductivity power cables and wires in energy and electric machines using superconductors.
