Al2O3 (Aluminum Oxide, Alumina)

Notes. In ceramics, Al 2 O 3 comes up when technicians talk about glaze chemistry.It is an oxide mostly contributed by clays, feldspars and frits.As glazes melt oxides are liberated from materials and they form a glass structure. Al 2 O 3 is very important in that structure, mainly imparting stability to the melt and durability to the fired glass. Almost all glazes …

react with aluminum at the metal-oxide interface. At the same time, aluminum cations (positively charged ions) move outward from the valence band of the metal to react with water at the oxide-electrolyte interface. As a result, oxides are formed and continue to thicken at the two interfaces creating a dense layer of aluminum oxide …
