Activated alumina is a porous, solid form of aluminum oxide. It is also referred to as alumina or Al₂O_3. It’s a mineral that makes many precious gems, including ruby and sapphire. The bright colors in these gems are the result of impurities in this mineral.

Activated alumina is a material with a high surface area, and once all its existing moisture evacuates, it develops super absorption capabilities and can act as a great desiccant.

This blog will discuss all the important features of activated alumina and the applications where this mineral can be used.

Features of Activated Alumina

As mentioned above, activated alumina is an advanced form of aluminum oxide. However, the interesting thing that gives it its special properties is the pattern in which its molecules are connected.

When examined closely under a microscope, activated alumina comprises tiny, porous spheres that join together to create tunnels inside the material.

This unique structure makes activated alumina ideal for a variety of applications. One of the key features activated alumina offers is its ability to dry gases. The drying of volatile gases is vital to transport them safely. Due to its unique structure, activated alumina not only absorbs moisture from other gasses but bonds moisture inside the tunnels in its structure.  

Once moisture bonds with the structure of activated alumina, it can not be separated naturally. The moisture from inside the structure of activated alumina can only be untrapped through the heating process.

The unique features of activated alumina give it properties that make it suitable for many industrial applications, such as the removal of dangerous gases and the removal of toxic waste from the water draining from contaminated areas. Furthermore, it is a great option to purify water for industrial usage. In addition to all this, the most common use of activated alumina is as a great desiccant. It is widely used as a dehydrating agent during gasoline production and a desiccant to dry various natural gases.  

Activated alumina is of use in almost every industry. However, finding high-quality activated alumina at an affordable price can be tricky.
