Activated alumina is a granular form of alumina with high specific surface area and adsorption properties, and is therefore widely used in various fields.

1. Environmental purification; Activated alumina can be used as a catalyst or adsorbent in various waste gas treatment equipment. It can effectively remove harmful gases such as sulfur dioxide, carbon monoxide, nitrogen oxides, etc. Meanwhile, activated alumina can also adsorb and decompose organic substances, purifying the air environment.

2. Sewage treatment; Activated alumina also plays an important role in wastewater treatment. It can be used as a sewage treatment agent to remove heavy metal ions, organic matter, and suspended solids from water. By adsorption and catalytic oxidation reactions, harmful substances in wastewater can be converted into harmless substances, improving water quality.

3. Catalyst; Due to its excellent catalytic performance, activated alumina is widely used in the field of catalysts. It can serve as a carrier for catalysts and participate in various gas-phase and liquid-phase reactions. The high specific surface area and stability of activated alumina give it unique advantages in the field of catalysts.

4. Ceramic materials; Activated alumina can also be used to prepare ceramic materials. Due to its uniform particle size and dense structure, ceramics can have high strength and hardness. Meanwhile, activated alumina can also improve the wear resistance and corrosion resistance of ceramic materials.

5. Abrasive; Activated alumina is also widely used in the field of abrasives. It can be used as a cutting abrasive, polishing abrasive, and anti slip abrasive, etc. The high hardness and wear resistance of activated alumina make it effective in the field of abrasives.
