The unique features and the versatility of activated alumina balls makes them a necessary material to the industry. It is their ability to control moisture and contaminants that render them very critical in the treatment of water, purification of air and even in chemical processing.
In the present and the future industrial practices, it is expected that with the global growth of industrial environments, the usage of activated alumina will only increase, further highlighting its importance and usability. Below are certain features and applications of activated alumina balls that may enable organizations to utilize them as per their requirements.
What Are Activated Alumina Balls?
Activated alumina is a form of aluminium oxide (Al2O3) that is highly porous and is synthesized from aluminium hydroxide through dehydration. This activated alumina is manufactured by high-temperature roasting of hydrated aluminium oxide in an oven between 300 °C and 600 °C, allowing great surface area and high porosity. Such a structure enables it to adsorb several different ingredients with a high degree of effectiveness.
Key Properties
- High Porosity and Surface Area: Being a porous material, activated alumina has surface areas as high as (345 – 415 m²/gram) which makes it efficient in adsorption of both impurities and water.
- Chemical Stability: High chemical stability
- Mechanical Strength: Alumina balls are ceramics of high mechanical strength and resistance to thermal and mechanical shock.
- Non-Swelling: In contrast to some desiccants that change size and shape when moisture is absorbed, activated alumina remains unaffected.
Applications of Activated Alumina Balls
- Water Purification: There are many processes for purification of water like oxidation of iron, arsenic and fluoride removal through activated alumina. Thus, activated alumina is useful for fluoride rich areas and for water purification as it has very high adsorbing capacity.
- Air Purification: In air conditioning systems and dry air production for industrial use, activated alumina acts as a desiccant that draws out moisture from the air. This helps prevent Mold growth and ensures optimum humidity.
- Gas Drying: In the oil and gas sector, activated alumina plays a significant role in the drying of natural gas and other gases. It absorbs vapor water and thereby reduces the possibility of freezing and corrosion in the pipelines.
- Catalyst Support: Due to its surface area and thermal stability, it is also used as a support for catalysts in many reactions in the processes of chemical production. It makes the processes of several chemical reactions more effective and stable.
- Desiccants for Packaging: In addition, activated alumina balls are also found in many desiccants used for packaged foods which are maintained or transported in dry conditions.
- Industrial Applications: They are even applied in dialysis filters, as well as the filtration of industrial gases and removal of impurities from products made of petroleum.
Conclusion
Activated alumina balls are a crucial material used in many industries because of their special features and various uses. They are commonly used in water treatment, air purification, and chemical processing. Their main advantage is their ability to remove moisture and impurities, which is important for keeping products high-quality and operations running smoothly.
