Diffusion of Beryllium in Beryllium Oxide

The self-diffusion of Be in polycrystalline BeO was determined with radioactive Be7 at temperatures between 1570° and 1934°C. Following diffusion anneal, the samples were sectioned by grinding, and the one-dimensional diffusion-penetration of Be7 was determined by counting procedures. The data can be fitted by two straight lines on a log D vs. 1/T graph. The temperature region 1570° to 1730°C was fitted by D = 5.56 x 103 exp (-111,600/RT). The region 1730° to 1934°C was fitted by D = 6.14 x 10-2 exp (-66,100/RT). There was no evidence of grain-boundary diffusion.
