Kinetic demixing in α-alumina during cooling: Influence on the powder reactivity

We study the influence of the thermal treatment conditions on the solute cation redistributions at the near surface of alumina samples. Experiments have been done both on Mg-doped α-alumina powders and on Mg- and Ti-doped α-alumina single crystals. The results have been analyzed taking into account...
