The process for making Chevrel-phase PbMo6S8 superconducting tapes by reaction diffusion method and the properties of the tapes are reported. Mo tape reacts with H2S to form single phase Mo-S compound (MoS2 or Mo2S3, depends on the reaction temperature), then with Pb vapor to form single phase PbMo6S8 layers. The transition temperature of the layers are 13.0-14.5 K, the widths of the transitions are in the range of 0.15-0.20 K and Jc(6T, 4.2K) ≌1.9×l08A/m2.
