Alumina Production an overview ScienceDirect Topics

J. TONn, in Fundamentals of Aluminium Metallurgy, 2011. 2.7 Production of speciality aluminas. Although around 93% of alumina production is subsequently used as the feedstock in the smelting of the metal, there is a significant market for specialty aluminas. These markets lie in ceramics, particularly insulators and refractories, abrasives, catalysts, catalyst supports and absorbents.
