General description

Aluminum oxide is an amphoteric oxide of aluminum. It is also commonly referred to as alumina. It is used in a variety of applications such as adsorbents, catalysts, microelectronics, chemicals, and other high-technology fields.
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.
