HIGH TEMPERATURE SUPERCONDUCTOR HAVING MULTIPLE SUPERCONDUCTING LAYERS, AND HIGH TEMPERATURE SUPERCONDUCTOR MANUFACTURING METHOD FOR SAME

摘要

The present invention relates to a method for manufacturing a high temperature superconductor, and a high temperature superconductor having multiple superconducting layers using same. The present invention comprises: a stacking step for stacking superconductors such that protection layers of a pair of superconductors including at least a substrate-superconducting layer-protection layer face each other; a bonding step for heat-treating the stacked pair of superconductors such that the protection layers facing each other are diffusion-bonded to each other to form a bonded protection layer; a peeling step for removing a layered structure on the upper side of a superconducting layer on one side of the superconductor on which the bonded protection layer is formed, thereby exposing the superconducting layer to the outside; and an outermost protection layer forming step for forming an outer protection layer, made of the same material as the bonded protection layer, on the upper side of the superconducting layer exposed to the outside through the peeling step. According to the present invention, it is possible to form multiple superconducting layers by easily stacking additional superconducting layers according to the required current density, and paste of the same material as the protection layers can be filled into gaps between the stacked protection layers through a paste filling process and heat-treated together with the protection layers, such that there is an advantage in that the superconducting layer and the substrate can be effectively separated in the process of peeling the substrate.
