The formation of intercalation compounds from sulfur fluoride SF6 and layered substrates was observed. The process is accelerated if the substrate had been preexposed to SF6 partly decomposed by electric spark discharges. The amount of intercalated SF6 decreases in the series graphite > molybdenum disulfide > boron nitride. The promotion effect is explained by exfoliation of the substrate due to highly reactive fission products of SF6.
