General description

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.
We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Aluminum oxide serves as a multifunctional additive or coating in lithium-ion batteries, helping stabilize electrode–electrolyte interfaces, suppress side reactions, improve thermal stability, and extend cycle life. By enabling safer, longer-lasting cells, it reduces material waste and energy use across the battery lifecycle. Click here for more information.

Application

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