Used as a catalyst support in refining and petrochemical processes due to its high surface area and thermal stability. Common in hydroprocessing units where it helps disperse active metal components like nickel or molybdenum. Also serves as a binder in catalyst formulations, improving mechanical strength and porosity. Applied in adsorbents for gas purification and in ceramic coatings for its ability to form durable, heat-resistant layers. Utilized in the production of advanced ceramics and as a precursor for aluminum-based materials.
