Superconducting ribbons of SnMo/sub 6/S/sub 8/ and PbMo/sub 6/S/sub 8/ have been produced using a one step vapor transport technique. In this process Sn or Pb vapor and H/sub 2/S gas react at the surface of a Mo substrate at elevated temperatures to form a uniform coating of Chevrel phase. SEM micrographs show the film on the ribbons to be composed of small (less than or equal to0.5 ..mu..m) single-crystal rhombohedra of Chevrel phase. Critical currents for the SnMo/sub 6/S/sub 8/ ribbons are similar to that achieved in PbMo/sub 6/S/sub 8/ by other techniques (approx.1 x 10/sup 4/ A/cm/sup 2/ at 19 T and 4.2 K). The performance of our PbMo/sub 6/S/sub 8/ is severely degraded. An explanation for this is based on larger intrinsic strain effects in the PbMo/sub 6/S/sub 8/.
