Abstract
For this feasibility study, superconductor/silver/PSZ (partial-stablized-zirconia) composite samples with a superconductor composition of Bi/sub 1.84/Pb/sub 0.34/Sr/sub 1.91/Ca/sub 2.03/Cu/sub 3.06/O/sub y/ (2223), were fabricated via the doctor-blade technique. It was found that the densification and alignment of 2223 grains along the composite interface was crucial to achieving high critical current densities (J/sub c/). The effects of heat treatment and uniaxial hot pressing pressure were investigated to develop a scheme to maximize J/sub c/. The highest zero-field J/sub c/ value of 3/spl times/10/sup 7/A/m/sup 2/ at 77 K was obtained in a uniaxial hot pressing at 1108 K. >
