About the Activated Aluminum Oxide：
High specific surface area and porosity
Activated alumina has a very high specific surface area, usually reaching hundreds or thousands of square meters per gram. This high specific surface area enables activated alumina to have many active sites and adsorption capacity. At the same time, activated alumina is also porous, and its pore size is widely distributed, including micropores, mesoporous, and macropores, which provides a basis for its application in adsorption, catalysis, and separation.
Thermal and chemical stability
Activated alumina has good thermal and chemical stability. Under high-temperature conditions, the structure and properties of activated alumina can remain stable, and it is not easy to decompose or phase change. In addition, activated alumina is inert to many chemicals and is not easy to react with, so it can maintain its original properties in various chemical environments.
Activated alumina has strong adsorption properties and can absorb various gases, liquids, and solutes. Its adsorption properties are mainly due to its high specific surface area and porous structure, as well as the active site on the surface. Activated alumina can absorb heavy metal ions, organic matter, pigment, and other pollutants in water, as well as harmful gases and odors in the air.
Activated alumina also has catalytic properties and can be a catalyst or carrier. Its catalytic performance is mainly due to its high specific surface area and porous structure, as well as the active site on the surface. Activated alumina can catalyze many chemical reactions, such as oxidation, reduction, acid-base, and so on. At the same time, it can also be used as a carrier of metal catalysts to improve the dispersion and stability of metal catalysts.
Mechanical strength and wear resistance
Activated alumina has good mechanical strength and wear resistance and can maintain the stability of its structure and properties under various mechanical stress and wear conditions. This allows activated alumina to have a long service life and good durability in various industrial applications.
At the same time, it can also be used as an essential material in environmental protection fields such as wastewater treatment and waste gas treatment to remove pollutants and protect the environment.
Activated alumina has certain renewability, and its adsorption and catalytic properties can be recovered by regeneration treatment. This enables activated alumina to reduce costs and improve economic benefits during use.

Production Method the Activated Aluminum Oxide：
Raw material preparation
First, raw materials such as sodium aluminate and aluminum sulfate must be prepared. Sodium aluminate is a compound containing alumina, while aluminum sulfate is a compound containing sulfate.
Mixture of ingredients
Sodium aluminate and aluminum sulfate are mixed proportionately to prepare an ingredient solution. This solution contains all the ingredients needed for the synthesis of activated alumina.
The mixture solution is a crystallization reaction; under specific temperature and pressure conditions, aluminum, sodium and other elements in the solution will undergo chemical reactions to generate activated alumina crystals. This reaction requires temperature, pressure, and reaction time control to ensure the crystal quality and purity of the resulting molecular sieve OX480.
Washing and drying
After the crystallization reaction, the resulting crystals must be washed and dried. Washing removes impurities and residues on the crystal surface to ensure purity; drying separates the crystal from the solution for subsequent processing and treatment.
Screening and packaging
The dried crystals need to be sieved to remove crystals of different sizes to ensure the quality and specifications of the product. Finally, the sieved crystals are packaged for transportation and use.
