Formation of Aluminum Oxide

4Al + 3O2 → 2Al2O3

Genel Bakış

Aluminum reacts with oxygen to form aluminum oxide (alumina). While aluminum appears resistant to corrosion, it actually oxidizes instantly in air, forming a thin protective oxide layer that prevents further reaction. Powdered aluminum burns vigorously in oxygen.

Günlük Örnek

The dull gray coating on aluminum cans and foil is a thin layer of aluminum oxide that protects the metal from further corrosion.

Endüstriyel Önemi

Aluminum oxide is used as an abrasive (corundum), in ceramics, as catalyst support material, and as the starting material for aluminum metal production via the Hall-Heroult process.
