The porous-frit technique was used to investigate the self-diffusion of 36Cl in molten reagent-grade material. The data for 330 to 526C could be described by:

D (cm2/s) = 0.137 exp[-16.3(kcal/mol)/RT] Self-Diffusion in Molten Zinc Chloride. C.A.Sjöblom, A.Behn: Zeitschrift für Naturforschung, 1968, 23a, 495-7
