The Introduction Of Activated Alumina

Activated alumina belongs to the chemical alumina category. It is a porous, highly dispersed solid material with a large surface area and is mainly used for adsorbents, water purifiers, catalysts and catalyst carriers. According to different uses, the raw materials and preparation methods are different.

Activated alumina can be used as a desiccant, with high water absorption, fast drying and regenerable. Its microporous surface possesses properties required for catalysis, such as adsorption performance, surface activity, and excellent thermal stability.

Among the reasons for the widespread acceptance of alumina in these applications are its low cost, chemical and physical resistance, regenerability and high capacity for retaining water.
