The diffusion of Cl in undoped material under near-saturation Cd overpressures or minimum total-pressure conditions, was studied at 520 to 800C by using radiotracer techniques. It was found that, at a given temperature, there was no appreciable difference between the diffusivities measured under the various partial pressures. Under saturation conditions, the results could be described by:

D (cm2/s) = 7.1 x 10-2 exp[-1.60(eV)/kT]

It was concluded that the Cl diffused via a mechanism which involved the neutral defect pair.
