The surface state of a-Al2O3 powders cannot be regarded as a-Al2O3 but a hydrated state, and that thenature of this hydrate cannot be considered universal among different a-Al2O3, even produced by the same production method. Oneof these reasons is that water can be incorporated in the a-Al2O3 crystal structure resulting in the formation of aluminum hydroxidessuch as gibbsite. Although much research has shed light on the Al2O3-water interface and charging of a-Al2O3 surfaces, there isstill much that we need to better understand a-Al2O3 structural property and surface characteristics. In this paper, general viewof crystal-structural properties, manufacturing methods of high purity a-Al2O3, and surface characteristics on a-Al2O3 powders areintroduced., application/pdf}, pages = {23--31}, title = {Structural Properties and Surface Characteristics on Aluminum Oxide Powders}, volume = {9}, year = {2010}, yomi = {シライ, タカシ and フジ, マサヨシ} }
