Aluminum oxide (Al₂O₃) based nanopowder is a metal oxide based nanosized material that can be used in a variety of industrial applications. It can be prepared by the hydrolysis of the alkoxide of Al₂O₃ and calcination of particles in the presence of stabilizing agents.

Al₂O₃ nanopowder can be used for a wide range of applications, such as ceramics, aerospace, wastewater treatment, abrasives, paints, catalysts, and flooring materials.
