Activated alumina powder is an indispensable element of industrial packaging, offering moisture protection while being easily recyclable and regenerated, which reduces operating costs and maintenance expenses.
Activated alumina is an aluminum oxide composed of highly porous spheres. As such, it is amphoteric; meaning that it can work effectively with both acidic and basic chemicals.
Moisture Adsorption
Activated alumina is an efficient desiccant that helps remove moisture from the air. It features a high specific surface area, meaning that more molecules than its weight can be attracted by it.
This property makes activated carbon an excellent choice for various applications, including water purification in factories, sewage treatment plants and residential homes – such as the removal of lead, arsenic, fluoride and other contaminants – as well as being an efficient gas adsorbent (including oxygen absorption).
Chemically inert and non-reactive with most chemicals, it does not leach out or release harmful compounds during purification processes. Furthermore, its mechanical strength makes it highly impact-resistant.
Moisture control is essential in many industrial processes and pharmaceutical packaging operations, from corrosion prevention to quality of the final product. Medication, in particular, can become vulnerable to humidity levels causing reduced efficacy or degradation over time.
Activated alumina has the power to absorb moisture and protect medications in their optimal state, keeping them in top shape for your application. At FEECO’s Innovation Center we provide thermal and agglomeration testing in order to guarantee product readiness – simulating production conditions while testing various preparation methods, which help optimize final products.

Sterilization
Activated alumina has powerful sterilization properties and can be used to purify water, gas and vapours. It has become a valuable addition in the pharmaceutical industry as it maintains an ideal moisture-free environment inside packages of medications, protecting their efficacy and shelf life while simultaneously helping prevent unwanted microbial growth that thrives in humid conditions.
Alumina’s high porosity and surface area enables it to absorb an abundance of substances through its porous structure, making it useful in many different applications. Alumina is particularly adept as a desiccant, which makes it popularly employed in natural gas and petrochemical production facilities to remove moisture, carbon dioxide, and trace impurities from gas streams and vapour streams.
Activated alumina is widely used as a desiccant in the production of hydrogen peroxide for cleaning applications and to dry out compressed air systems. Furthermore, activated alumina plays an integral role in water treatment processes by adsorbing fluoride, arsenic, and selenium from drinking water sources.
Activated alumina’s unique combination of physical and chemical properties make it a valuable resource across several industries, from pharmaceutical packaging to catalyst support in petrochemical production. Manufacturers can customize its performance for different applications by controlling factors like length and peak temperature of its calcination process to control its pore size and surface area, thus tailoring this adsorbent’s performance exactly according to need.
Disinfection
Activated alumina’s ability to capture and destroy bacteria, viruses and other pathogens makes it an excellent disinfectant suitable for water treatment, gas purification and desiccant applications. Due to its high specific surface area and abundant pore network, activated alumina is extremely effective at trapping and neutralizing various contaminants that enter its pores.
Activated alumina’s powerful adsorption capabilities enable it to effectively remove fluoride and arsenic from drinking water sources, as well as being utilized in natural-gas processing and petrochemical production to remove dry gases and vapour streams, thus preventing corrosion while guaranteeing product quality.
activated alumina is an integral component in the manufacturing of electronic components and pharmaceutical products due to its versatility and wide application. By trapping moisture and other gases, it prevents corrosion while prolonging shelf life; decreasing risk of malfunction or degradation in delicate items.
It is crucial that when handling activated alumina powder, safety guidelines are strictly observed in order to avoid skin contact, inhalation of airborne particles or any other factors which could result in injury or illness. When working with activated alumina powder it is advised to wear personal protective equipment (PPE), such as chemical resistant gloves and goggles or face shield. Proper ventilation must also be ensured in order to minimize dust accumulation; any spillages must also be immediately cleared up to reduce slip hazards and eliminate potential slip hazards.
Cleanup
Activated alumina’s large surface area and porous structure enable it to absorb significant quantities of moisture from its surroundings, acting as an efficient desiccant to keep products dry while preventing mold, mildew, or other unwanted contaminants from growing inside packages.
Activated alumina (Al2O3), the same chemical component found in diamonds and sapphires, features an extremely high surface area characterized by many small pores that look similar to tunnels running throughout its structure. Due to this porosity, activated alumina can adsorb an extensive array of materials including ions and molecules.
Due to its superior adsorption capacity, activated carbon can be used in an array of water treatment applications for fluoride, arsenic and selenium removal from drinking water sources as well as degradation acids found in transformer oils, lubricating oil and refrigerants.
Based on its application, activated alumina can come in beads, pellets, granules or powder form. Particle size typically impacts its contaminant removal capacity as well as flow rate and pore structure; consequently it’s important that activated alumina remains in good condition by performing regular maintenance like adding caustic soda (1 percent NaOH) to water for cleaning purposes.
