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 efficiency, surface activity and good thermal stability.

It has high activity because it is porous and has a lot of surface area. The adsorption abilities of activated aluminum are used in the petrochemical industry, fertilizer, 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 polymers in composites, there is a poor wettability, a low composite quality, and a performance that is far below what is expected. 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. Surface coating metal modification can be used to improve the performance of metal alumina composite materials.
