Synthesis of Alumina Using Aluminum Acetate

Article Preview

Abstract:

Alumina is a material used in a wide range of applications, including refractories, structural materials, sensors, catalysts, etc. Several synthesis methods are available for the production of submicrometric and nanometric alpha alumina. However, there is few studies on the use of acetate for the synthesis of alumina. Thus, the present work has as aim the synthesis of alumina powders using aluminum acetate. The precursors were obtained from the decomposition of aluminum acetate under temperatures of 650oC and 850oC, resulting in an amorphous precursors and gamma-alumina. These materials were submitted to dissolution and calcination. Based on the results, it is observed a reduced in the temperature formation of alpha phase, at around 900oC, when using the adopted methodology of synthesis. Amorphous precursor was more susceptible to the synthesis procedure used and generated alpha alumina in lower temperatures.
