A liquid-phase processing method has been developed to manufacture bulk YBa_2Cu_3O_x/Ag superconducting composites with large current carrying capacity and enhanced ?mechanical properties. Transport critical current density of 10,000 A / cm^2 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/cm^2 is obtained. This composite has a Young's modules of 100 GPa and a fracture stress of 70 MPa, which are substantially higher than those of sintered 1-2-3 superconductor.
