Abstract:

Diffusion coefficients for Zn2 in single-crystal MgO were determined in the temperature range 1000-1650C were 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 electron volts, and D sub o 0.0000148 21. cmsec. 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. Author
