What Is Activated Alumina?

Activated Alumina

Activated alumina is a type of aluminum oxide. The material is used in many industries and for various purposes. The most important use of this material is in water treatment as it helps filter out elements that are not suitable for drinking water such as:

  • Selenium

  • Fluoride

  • Arsenic

Besides that, it is also used in the gas and oil industries as a catalyst. The properties of this material make it ideal for these industries as they can get the most use out of it.


Characteristics Of Activated Alumina


(1) Large specific surface area: activated alumina has a high specific surface area. By reasonably controlling the sintering system of alumina, activated alumina with a specific surface area of 360m2/g can be prepared. The colloidal aluminum hydroxide obtained from the decomposition of NaAlO2 is used as raw material to prepare activated alumina. Its pore size is very small, and its specific surface area can be as high as 600m2/g.

 

(2) Adjustable pore size structure: Generally speaking, products with medium pore size can be prepared by baking pure aluminum hydroxide. The product with smaller pore size can be prepared by preparing activated alumina with aluminum glue, and the activated alumina with larger pore size can be prepared by adding some organic substances, such as ethylene glycol and fiber, after combustion.

 

(3) The surface is acidic and has good thermal stability.

 

Function of Activated Alumina


Activated alumina belongs to the category of chemical alumina, which is mainly used as adsorbent, water purification agent, catalyst and catalyst carrier. Activated alumina has selective adsorption ability for gas, water vapor and water in some liquids. After adsorption saturation, it can be revived by heating at about 175 ~ 315 to remove water. Adsorption and reactivation can be carried out many times.

All these properties enhance its ability as an adsorbent. Activated alumina must go through a controlled production process to achieve these functions. XINTAO's activated alumina adopts the most advanced production technology and equipment, strict quality inspection process, to ensure the quality of activated alumina, sold for nearly 20 years of activated alumina, we guarantee 0 after-sales.
