The serial sectioning technique was used to study the diffusion of 45Ca in single crystals which contained about 18ppm of divalent impurities. At 260 to 440C, the data could be described by:

D (cm2/s) = 2.7 x 10-1 exp[-1.07(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)
