The surface decrease and isotope exchange techniques were used to study the diffusion of 36Cl in single crystals. Electrical conductivity measurements were also performed on doped and undoped crystals. It was concluded that the predominant imperfections were anionic Frenkel defects, that the ionic transport was predominantly anionic, and that the experimental correlation factors could not distinguish between interstitialcy and vacancy mechanisms; although general considerations favored the latter. The diffusivity at 700C was 3 x 10-7cm2/s. The behavior of the diffusion and conductivity at temperatures below 500C indicated that defect complexes were formed.
