Diffusion coefficients for Zn2+ in single‐crystal MgO have been determined in the temperature range 1000°—1650°C from concentration gradients obtained with the aid of electron microbeam probe spectroscopy. The variation of the diffusion coefficients with temperature yields an activation energy for diffusion of 1.85 eV, and D0=1.48 10−5 cm2/sec. The oxides display appreciable solid solubility in one another, but the range of solid solution of ZnO in MgO greatly exceeds that for MgO in ZnO.
