Alumina oxide powder is made of aluminum hydroxide by suspended roasting, rapid dehydration and rapid cooling. It is a porous, high specific surface area alumina material with loose structure, controllable pore size distribution, rich hydroxyl groups on the surface and high activity.
High specific surface area – strong adsorption capacity and high catalytic activity.
Porous structure – suitable for adsorption of molecules of different sizes (such as water, fluorine, VOCs).
Good thermal stability – suitable for high temperature catalysis or regeneration.
Rich in hydroxyl groups on the surface – enhance polarity and adsorption capacity.
Amphoteric material – can adsorb acidic and alkaline substances.
High mechanical strength – wear resistance.
Renewable – can be reused after treatment.
Chemical stability – resistant to weak acids and weak bases.
Insulation – can be used in electronics, ceramics and other fields.

Note: We can produce alumina oxide powder according to your required data.
Adsorbent: used to dry gases and liquids (such as air, hydrocarbons), remove water molecules and impurities;
Catalyst carrier: loads metals or active components, used in petrochemicals (such as hydrogenation, desulfurization), automobile exhaust purification, etc.;
Water treatment: adsorbs harmful substances such as fluoride ions and arsenic, purifies drinking water and industrial wastewater;
Ceramics and fillers: enhance material performance, used in refractory materials, electronic ceramics or composite materials;
Others: such as chromatographic separation, pharmaceutical sustained release and mercury removal agents in the chlor-alkali industry.
Its performance can be further optimized by regulating pore size and surface modification to meet specific needs.
●Avoid moisture, avoid scrolling, throw and sharp shocking during transportation, rainproof facilities should be readied..
●It should be stored in dry and ventilated warehouseto prevent contamination or moisture.
