The Difference Between Activated Alumina and Modified Alumina |

Difference between activated and modified alumina

Activated alu is a porous solid material that has a high surface area and is highly dispersed. The microporous nature of the surface makes it suitable for catalysis. It can also be used to carry catalysts and as chemical reaction catalysts.

Activated alumina is highly active due to its porous structure, large specific area and unstable transition state. The petrochemical, fertilizer, and other industries use activated alumina as a gas liquid desiccant. Activated Alumina is a fluorine-filter material with a long service lifetime. This means that activated Alumina can be used in a wider range of industries.


Modified alumina. Because of differences in chemical and physical properties, alumina, polymer and metal materials have poor wettability and composite quality. The composite material’s performance does not meet the theoretical standards. A modified functional, inorganic, filler is combined with organic polymer to increase the wettability at the interface. It also makes the structure uniform and becomes a polymer function filler. The result can improve the performance of the composite alumina. The performance of the metal-alumina composite material can be improved by modifying the surface of the alumina dust particles.
