Gamma -Al2O3 with small size, high activity and low melting temperature, it can be used for producing synthetic sapphire with the method of thermal melting techniques; the g-phase nano-Al2O3 with large surface area and high catalytic activity, it can be made into microporous spherical structure or  honeycomb structure of catalytic materials. These kinds of structures can be excellent catalyst carriers. If used as industrial catalysts, they will be the main materials for petroleum refining, petrochemical and automotive exhaust purification.
