Wires of PbMo/sub 5.1/S/sub 6/ have been prepared by drawing sintered and powdered ternary sulfide in a metal sheath. Subsequent annealing at high temperatures (850-1000 /sup 0/C) is necessary to restore T/sub c/ to its maximum value approx.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 fields B/sub c2/ (4.2 K) approx. =51 T of these wires are the same as for the best powder samples, but current densities, J/sub c/ (4.2 K, 4 T) approx. (1-5) x 10/sup 7/ A/m/sup 2/, are disappointingly low.
