It was noted that many kinds of experimental techniques, such as the long capillary method and the shear cell method, had been devised for ground-based research on the measurement of diffusion coefficient in high-temperature melts. The shear cell technique, coupled with micro-gravity conditions had recently been applied to high-temperature metallic melts. This technique permitted the measurement of the diffusion coefficient to high precision. The current status of the development of the authors’ shear cell technique was summarized, and new results were presented - as being typical terrestrial experiments - for liquid Ag–Au alloys.
