The self-diffusion coefficient, DS in liquid Sn was measured by a long capillary method in the microgravity environment of the space shuttle, and the validity of a microgravity effect was confirmed for the measurements of diffusion in melts with high melting temperatures. The data of this DS under microgravity were well reproduced by calculations, particularly in the case closely related to liquid structures. A systematic microgravity experiment is required to obtain further insight and to develop a model for diffusion in group IVB liquids.
