Difference between modified and activated 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, surface activity, thermal stability and good thermal resistance.
It has high activity because it is porous and has a lot of surface area. 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, and gas purification. 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 composite materials, 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. At the same, surface coating metal modifications of alumina powder can improve performance of metal alumina composite materials.
