The most effective way for liquid diffusion measurements is the shear cell technique. In this method, a diffusion couple is only joined at a target temperature to avoid diffusion during heating and cooling processes, and to avoid solidification effects. Numerical simulation confirmed that the misalignment of a diffusion couple hinders precise diffusion experiments. Hence, the liquid sample should be observed during the shear cell experiments to confirm the correct alignment. A direct X-ray observation system was thus specifically developed and the impurity diffusion of Au in liquid Ag was successfully measured using this apparatus.
