Serial sectioning techniques were used to obtain 65Zn tracer diffusion data for high-purity single crystals. It was shown that the diffusion of Zn2+ tracer proceeded substitutionally at 209 to 441C. For 209 to 350C, it was shown that:

D (cm2/s) = 5.3 x 10-2 exp[-0.77(eV)/kT]

The data for 352 to 441C were described by:

D (cm2/s) = 4.5 x 100 exp[-1.01(eV)/kT]

The best linear fit to the solute diffusion data ([348] to [365]) yields:

Mn: Ln[Do] = 0.87E – 22.7 (R2 = 0.99)
