抄録

A liquid-phase processing method has been developed to manufacture bulk YBa₂Cu₃O_x/Ag superconducting composites with large current carrying capacity and enhanced mechanical properties. Transport critical current density of 10,000 A/cm² is obtained in nominal 15 wt.% Ag composite using continuous direct current at 77 K and zero applied field. Using a pulsed current of 2 ms duration, a critical current density of 22,000 A/cm² is obtained. This composite has a Young's modulus of 100 GPa and a fracture stress of 70 MPa, which are substantially higher than those of sintered 1–2–3 superconductor.
