General description
Aluminum oxide (Al2O3), also known as alumina. It is commonly used in various rubber, plastics, ceramics, and refractory materials for reinforcement hardening. It can also be used as a filler or component in polymer or inorganic composite materials, as a catalyst or catalyst support, as an adsorbent, etc.
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
Aluminum oxide is used as
- Filler for plastics and a common ingredient in sunscreen and many cosmetics.
- As a catalyst for alcohol dehydration in the Claus process.
- As a catalyst in the conversion of urea to ammonia.
Features and Benefits
Aluminum oxide has:
- High porosity
- High surface area
- Acidic and basic property

Water-based drilling fluids are extensively used for drilling oil and gas wells. However, water-based muds cause clay swelling, which severely affects the stability of wellbore. Due to two adsorption positions, it is expected that cationic gemini surfactants can reduce the
