Abstract
A rate equation of grain growth and a distribution function of grain radii were derived from the statistical viewpoint. The derived equation and function were successfully applied to the analysis of both the grain growth and grain radius distribution data in Cr-doped MgO. The diffusion coefficients of this sample were 103 times larger than the oxygen self-diffusion coefficients in pure MgO.
