(1) Activated alumina/Aluminum Oxide can be used as an efficient desiccant for trace amounts of water;

(2) High-purity alumina/Aluminum Oxide is prepared by different processes, and can be used in the fields of sapphire crystal raw materials for LEDs, trichromatic phosphors, long-lasting phosphors, high-pressure sodium lamps, glass additives, electronic ceramics, catalyst carriers, etc.

Due to its better physical and chemical properties, the corresponding customers can get more satisfactory use results;

(3) Hydrated alumina/Aluminum Oxide is mainly used as a raw material for catalyst carrier activated alumina;

And can also be used as a forming binder for molecular sieves and silicate refractory fiber products, such as a binder for semi-synthetic rare earth Y-type molecular sieve cracking catalysts, as a catalyst for alcohol dehydration to ethylene and ethylene oxide catalysts, etc.

(4) Low-sodium alumina/Aluminum Oxide is a high-purity, fine а-alumina powder with uniform grain size.

Low-sodium alumina/Aluminum Oxide is mainly used in the polishing of metal, glass and various ceramic products and as a firing aid for non-oxide ceramics.
