Activated Alumina Powder is a porous material with alumina (Al₂O₃) as the main component, prepared by a special process. It has a high specific surface area and activity and is widely used in adsorbents, desiccants, catalyst
carriers and basic raw materials for high-performance materials.
Features of Activated Alumina Powder
Adsorption characteristics
Strong hygroscopicity: can quickly absorb moisture in the environment and is an excellent desiccant.
Selective adsorption: has a specific adsorption effect on certain gases (such as hydrogen sulfide, carbon dioxide, etc.).
Catalytic characteristics
Activated alumina powder has high surface activity, which can enhance the dispersion and reaction efficiency of the catalyst.
Can be used for fine chemical applications such as defluorination, desulfurization and dechlorination.
Environmental characteristics
Environmentally friendly materials: recyclable and long service life.
Non-toxic and harmless: suitable for food-grade and pharmaceutical-grade applications, such as water treatment, drug drying, etc.
Physical characteristics
Strong particle plasticity: easy to process into different shapes, such as spheres, rods or powders, to meet a variety of industrial needs.
Good dispersibility: uniform fineness, suitable for applications such as ceramics and coatings.
