A sectioning technique was used to study the diffusion of 22Na in a diffusion couple which consisted of NaCl and NaBr single crystals, with their (100) crystal planes in contact. The self-diffusivity increased from 8 x 1010cm2/s, to a maximum of about 9 x 1010cm2/s at about 25at%NaCl, and then fell to about 3.4 x 1010cm2/s for pure NaCl.
