High‐density bulk Pb1−xSnxMo6S7.6 (0≤x≤1) samples have been made by hot isostatic pressing at the relatively low temperatures of 800 and 900 °C. Critical current densities, computed from magnetization data taken at various magnetic fields and temperatures, show excellent temperature scaling indicating that a single pinning mechanism is present. The magnetization of all samples scales with size, showing that full density samples are not granular. Samples sintered without pressure at higher temperatures did not achieve full density and did not exhibit good size scaling of the magnetization, thus indicating only percolation connections across the sample in this case. We conclude that there is no intrinsic granularity in these Chevrel phases even though their coherence length is short.
