摘要：

TlBa2Ca2Cu3Ox powders were synthesized from a mixture of oxides and carbonates. Tl2O3 was reacted with a complex oxide with an overall composition of Ba2Ca2Cu3Ox. All reactions were carried out in flowing O2, with the Ba2Ca2Cu3Ox formed at a reduced pressure of almost-equal-to 2.5 x 10(2) 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 x 10(3) A cm-2.
