Difference between activated and modified alumina
It is a highly porous solid with a high surface area. Its microporous, highly dispersed surface is a material with the properties required for catalysis. These include adsorption and surface activity as well as thermal stability.
Because it is porous and has a high specific surface area in an unstable state of transition, activated aluminum has a lot of activity. It is also used in the petrochemical industry, as well as other industries. Because it has good adsorption, it 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. At the same, surface coating metal modifications of alumina powder can improve performance of metal alumina composite materials.
