In the case of high purity α-Al2O3 powder, the surface may contain an aluminum hydroxide phase, which may bring differences in surface property of α-Al2O3 powders. The aluminum hydroxide phase present on the surface sometimes leads to porous structure in sintered bodies. Therefore, the investigation for hydration ability of powder surfaces is very important for ceramic manufacture. In this paper, the effects of manufacturing process of commercial high purity α-Al2O3 powders on their surface characteristics are discussed.
