Abstract

TlBA2Cu3Ox and Tl2Ca2Cu3Ox powders were synthesized, loaded into Ag tubes, and worked into wires and tapes by drawing and rolling. All processing outside of furnaces was in a dry-N2 glovebox. All heat treatments were performed in O2. The Ag-clad wires fabricated from these powders exhibited onset of superconductivity at ≈118 K and critical current densities at 77 K of 2 × 103 to 4 ×103 A/cm2.
