What is alumina?
Alumina is aluminum oxide produced from bauxite by a chemical process. It is a white powdery material that looks like granulated sugar. Alumina is an intermediate step in the production of aluminum from bauxite and is also a valuable chemical on its own. Alcoa is the world’s leading supplier of alumina, and Alcoa aluminas exceed expectations for quality and performance while providing the basic materials to improve products and processes.
