Abstract

The rate of oxygen diffusion at 1400 degree C into pure, deformed, and scandium-doped MgO was measured using a secondary-ion mass spectrometer with **1**6O** minus primary ions as sputtering agents to monitor the penetration of **1**8O into the sample from an **1**8O-enriched surface layer. In samples doped with scandium, oxygen, diffusivity did not differ significantly from the value, 1. 3 multiplied by 10** minus **1**5 cm**2/s, found for the pure sample. In deformed samples, the diffusion coefficient was 5. 8 multiplied by 10** minus **1**5 cm**2/s.
