The rate of oxygen difusion at 1400°C into pure, deformed, and scandium‐doped MgO was measured using a secondary‐ion mass spectrometer with 16O‐ primary ions as sputtering agents to monitor the penetration of 18O into the sample from an 18O‐enriched surface layer. In samples doped with scandium, oxygen diffusivity did not differ significantly from the value, 1.3 × 10‐15 cm2/s, found for the pure sample. In deformed samples, the diffusion coefficient was 5.8 × 10‐15 cm2/s.
