Wires of PbMo5.1S6have been prepared by drawing sintered and powdered ternary sulfide in a metal sheath. Subsequent annealing at high temperatures (850–1000 °C) is necessary to restoreTcto its maximum value ∼14.4 K. The sheath material must not react with and reduce the sulfide, and of the common metals this limits the choice to silver. Critical fieldsBc2(4.2 K) ?51 T of these wires are the same as for the best powder samples, but current densities,Jc(4.2 K, 4 T) ∼ (1–5) ×107A/m2, are disappointingly low.
