Surface decrease and isotope exchange techniques were used to study diffusion of 90Sr in monocrystals. Conductivity measurements were also performed on doped and undoped crystals. The predominant imperfections were anionic Frenkel defects, that the ionic transport was predominantly anionic. The experimental correlation factors could not distinguish between interstitialcy and vacancy mechanisms. The diffusivity at 700C was 10-13cm2/s, while that at 800C was 3 x 10-10cm2/s. The behavior of the diffusion and conductivity at temperatures below 500C indicated that defect complexes were formed.
