Abstract:
     The present invention relates to the liquid-nitrogen temp. region super-conducting wire and strip of yttrium-, barium-and copper-oxidate system and its preparation process. The process is: first, to bind together the yttrium-, barium-and copper-oxidate system with high molecular compound to form a pioneer-stock which is easy to process into various shapes and sizes, and then, to put the stock into heat-treatment to form the wire and strip product. The practical liquid-nitrogen temp. region superconducting wire and strip are expected to be used in electric power transmission, information energy transfer, superconducting magnet and magnetic suspension train and all the other fields requiring superconducting material.
