The diffusive behavior of 82Br was studied at 400 to 700C. The results could be described by:
D (cm2/s) = 3.0 x 104 exp[-2.61(eV)/kT]
D.K.Dawson, L.W.Barr: Proceedings of the British Ceramic Society, 1967, 9, 171-9
The best linear fits to the solute diffusion data ([336] to [347]) yield:
Ar: Ln[Do] = 0.77E – 13 (R2 = 0.98); Br: Ln[Do] = 0.49E – 18.3 (R2 = 0.88);
He: Ln[Do] = 1.17E – 15.9 (R2 = 0.58)
