Difference between modified and activated Alumina

It is a highly porous solid with a high surface area. It is used as a catalyst carrier and chemical reaction catalyst because its microporous surface exhibits the required catalytic characteristics, including adsorption, surface activity, thermal stability etc.

Because it is in an unstable state of transition and has a porous surface, activated aluminum has high activity. 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 deodorizing, etc. 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. Modified functional inorganic is blended into organic polymer, which improves the wettability at the interface. It also makes the structure uniform and becomes a polymer filler. This improves the performance of alumina composites to some extent. At the same, surface coating metal modifications of the alumina particle powder can improve performance of metal alumina composite materials.
