LOW-RESISTANCE CONNECTION BODY FOR HIGH-TEMPERATURE SUPERCONDUCTING WIRE MATERIAL AND CONNECTION METHOD

摘要

A low-resistance connection body for high-temperature superconducting wire materials, having a high-temperature superconducting bulk body connected to a high-temperature superconducting wire material including a high-temperature superconducting layer. The fusion point of the high-temperature superconducting layer is higher than the fusion point of the high-temperature superconducting bulk body. At the connection sites between the high-temperature superconducting wire material and the high-temperature superconducting bulk body, the high-temperature superconducting layer and the high-temperature superconducting bulk body are in contact and the surface of the high-temperature superconducting bulk body that comes in contact with the high-temperature superconducting layer is crystalized as a result of crystal growth. Two high-temperature superconducting wire materials can be connected with low resistance, as a result of connecting each of the two high-temperature superconducting wire materials to one high-temperature superconducting bulk body.
