The diffusivity of O in liquid Sn at 800 to 900C was measured by using a modified coulometric titration method and a galvanic cell. It was found that the diffusion coefficient was independent of the O concentration, and could be described by:

D (cm2/s) = 3.42 x 10-3 exp[-8.1(kcal/g-atom)/RT]

These data were in agreement with previous result.

The best linear fit to the solute diffusion data ([1179] to [1181]) yields:

O(l): Ln[Do] = 0.38E – 8.9 (R2 = 0.82)
