Use

The oxide of aluminum is Al2O3. The naturalcrystalline mineral is called corundum, but thesynthetic crystals used for abrasives are designatedusually as aluminum oxide or marketedunder trade names. For other uses and as a powder it is generally called alumina. It iswidely distributed in nature in combinationwith silica and other minerals, and is an importantconstituent of the clays for making porcelain,bricks, pottery, and refractories.The crushed and graded crystals of aluminawhen pure are nearly colorless, but the finepowder is white. Off colors are due to impurities.American aluminum oxide used for abrasivesis at least 99.5% pure, in nearly colorlesscrystals melting at 2050°C. The chief uses foralumina are for the production of aluminummetal and for abrasives, but it is also used forceramics, refractories, pigments, catalyst carriers,and in chemicals.
