Used as a catalyst support in petroleum refining and chemical processing due to its high surface area and thermal stability. Common in the production of hydrocracking and hydrotreating catalysts. Serves as a binder in catalyst formulations, improving mechanical strength and porosity. Applied in ceramics and refractories for its ability to form durable, high-temperature-resistant structures. Utilized in adsorbents and separation processes because of its porous nature and controlled particle size. Also found in specialty coatings and polishing compounds where fine particle dispersion and reactivity are required.
