The interdiffusion of bromide ions at low concentrations in the molten chloride was measured by using gravimetric techniques. The results, at 503 to 820C, could be described by:

D (cm2/s) = 6.58 x 10-4 exp[-4.28(kcal/mol)/RT]

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

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