METHOD FOR PRODUCING LARGE FLAT HIGH-TEMPERATURE SUPERCONDUCTORS

摘要

The invention relates to the production of large flat high-temperature superconductors used for developing electrical articles. The inventive superconductors comprise high-temperature superconducting ceramic elements arranged inside a case in the form of layers, or the high-temperature superconducting ceramic elements are arranged inside the case in the form of layers with reinforcing elements arranged between said superconducting ceramic elements. After elements complex thermomechanical processing, the ratio of the surface area of the high-temperature superconducting ceramic elements to the maximum dimensions of the flat superconductor with respect to each layer of the superconducting ceramic elements, ranges correspondingly from 0.03 to 2 m. The critical current of the produced flat superconductors having the width value of up to 1m or up to 1.5 m using the reinforcing elements is not less than 560 ANGSTROM .
