Abstract:	A high-ir, superconducting tape joint between two Xg-clad 81-2223 tapes has been fabricated and characterized. Two pre-sintered tapes with one side of the silver striped were lapped and then wrapped by a silver foil. The complex was uniaxially pressed and followed b\- appropriate sinterin, yr to form a high-�l; superconducting tape joint. Transport critical current through the joint (icj) was determined at liquid nitrogen temperature. It KS found that the ratio of critical currents through the joint to that of the tape, I,j/I,, depended on the uniaxial pressure and the slntering conduction. For a test sample, I,j/I, reached 99~. Persistent current loops formed by Bi-2223 tapes have also been fabricated and tested. Joint resistance of a loop was determined 10 be - 4 x lo-l3 R after the initial decay time of 2 minutes.
