Note (General): Diffusion coefficients of Au in liquid Ag were measured carefully due to the diffusion couple method combined with the shear cell technique at the temperature of 1,300 K and 1,500 K. The shear cell was so-called modified long capillary crucible and is known to be the best method for the measurement of diffusion coefficient of liquids. The major cause of experimental error was derived from the liquid motion by the connection of liquid sample at the start of diffusion. In the present study, by changing the diffusion time from 300 seconds to seven hours, the time dependence of measured diffusion coefficient was clarified. The effects of the initial disturbance were sufficiently small in the case that the diffusion time was longer than two hours, for which the diffusion coefficient became independent on the diffusion time. The diffusion coefficient was compared with the theoretical value which was evaluated from the hard sphere mixture model.
