Superconducting Au-YBa/sub 2/Cu/sub 3/O/sub 7/ composites have been fabricated over a Au volume fraction range of 0--100%. Microstructure measurement indicates that Au and YBa/sub 2/Cu/sub 3/O/sub 7/ form well-separated phases. The superconducting transition temperature T/sub c/ was found unaffected by the presence of Au. The composites exhibit low normal state resistivity and much improved ductility. The results suggest that Au is an excellent metal host for making ultrafine YBa/sub 2/Cu/sub 3/O/sub 7/ granular solids.
