Type of article: Article

Summary

POSSIBLE FUTURE APPLICATION OF HIGH-CRITICAL TEMPERATURE SUPERCONDUCTORS MAKES NECESSARY THE DEVELOPMENT OF CONDUCTORS WITH HIGH CURRENT-CARRYING CAPACITY. AS FOR THE METALLIC SUPERCONDUCTORS COMPOSITE WIRES OR TAPES ARE NEEDED CONSISTING OF THE SUPERCONDUCTING MATERIAL, AN ELECTRICALLY STABILIZING NORMAL CONDUCTOR AND A MECHANICALLY REINFORCING MEMBER. SEVERAL OBSTACLES MUST BE OVERCOME IN THE DEVELOPMENT OF SUCH WIRES. THE MOST IMPORTANT PROBLEM IS THE LIMITATION OF THE CRITICAL CURRENT DENSITY IN POLYCRYSTALLINE CERAMIC BULK MATERIAL. MAIN REASONS FOR THIS LIMITATION ARE: ANISOTROPY OF SUPERCONDUCTING PROPERTIES, WEAK LINK CHARACTERISTICS, FLUX CREEP AND LOW PINNING STRENGTH.
