Aluminum oxide is an important chemical due to its many valuable properties such as hard ware resistance, good thermal conductivity, high strength and stiffness. Aluminum oxide is commonly referred to as alumina, possesses strong ionic interatomic bonding giving rise to its desirable characteristics. It can exist in several crystalline phases which all revert to the most stable hexagonal alpha phase at elevated temperatures. There are different types of Can which are used in everywhere. Most of the energy drinks are marked as canning (in which used mostly aluminum sheet). Can is a waste material which polluted our environment. We have prepared aluminum oxide from industrial Can by two methods. One is acid method and another one is alkali method. UV, thermo gravimetric (TGA), SEM and EDX analysis have been done. It has been showed that acid method is more feasible to prepare aluminum oxide.
