Abstract

TlBa2Ca2Cu3Ox powders were synthesized from a mixture of oxides and carbonates. Tl2O3 was reacted with a complex oxide with an overall composition of Ba 2Ca2Cu3Ox. All reactions were carried out in flowing O2, with the Ba2Ca 2Cu3Ox formed at a reduced pressure of approximately=2.5*102 Pa. All processing outside the furnace was in a dry-N2 glovebox. Ag-clad wires fabricated from these powders exhibited onset of superconductivity at 118 K and critical current densities at 77 K of about 4*103 A cm-2.
