Difference between activated and modified alumina

It is a highly porous solid with a high surface area. Its microporous, highly dispersed surface is characterized by adsorption, surface activity, and good thermal stability. This makes it a popular catalyst and carrier for chemical reactions.

Activated alumina, which has a porous surface, is in an unstable state of transition and has a large amount of specific surface, is very active. It is also used in the petrochemical industry, as well as other industries. Because it has good adsorption, activated aluminium can be used for a variety of purposes, including drinking water defluoridation, industrial wastewater coloring and deodorant. Alumina is used as a fluorine-filter material and has a very long service life.


Modified Alumina: Due to the different physical and chemical characteristics of alumina materials, metals, and polymer materials the wettability and composite quality of each component is poor. The performance of the composite material also falls short of theoretical indicators. The inorganic functional filler modified to be polymer-functional is blended into the organic polymer. This improves the wettability at the interface and makes the structure uniform. Alumina powder particles are coated with metal to improve their performance.
