In spite of having so many gas drying desiccants out there in the market, there has a strong significance why people (those who need to use these desiccants) are fond of activated alumina when it comes to dry out a warm gas appropriately. One of the prime reasons is that these balls are formulated with aluminum oxide which is highly porous and possess a tremendous surface area which let them soak up the gas and water molecules on a large scale. The surface normally ranges from 345-415 square meter/gm and this wide surface makes this element adsorb more gas, moisture, water vapor and humidity, even more than silica gel as well. For having such a higher capacity of gas consumption at an elevated temperature as well, it is an obvious choice for the various industrial purposes like; purification, isolations etc.

The alumina has a resistant power from thermal shock and abrasion, more so, they don’t get shrink, swell, soften and not even they disintegrate when completely saturated into gas. The element is formulated with aluminum hydroxide and the process is called dehydroxylation. Successful accomplishment of the process results in production of highly porous material with a huge surface area. It is made of aluminum oxide (Al2O3) and exhibits a high surface area compare to its weight and because of these, it has lots of small pores which run throughout it.
