Abstract
Analysis of Ti-containing heterogeneities in a hot-pressed Al2O3 has revealed changes in microstructure caused by oxidation that provide some insight regarding the effects of Ti on local grain growth. The most consistent hypothesis is that Ti4+ in solution compensates the Mg2+ ion taken into solution from the MgO additive, probably by forming dipoles, and negates the effect of Mg2+ on grain boundary drag.
