Description

General description

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.

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.

Application

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