Product Number: SC-RA
The activated alumina is made by calcining imported alumina and other materials mixed with special dosing technologies in a high-temperature rotary kiln. This alumina product possesses excellent whiteness, stable shrinking percentage, great compactness and so on, widely used in such sectors as electronic ceramics, engineering ceramics, insulating ceramics, high temperature roller, abrasive ceramics, refractories, etc.

The reactive alumina is able to selectively absorb moisture of gas, steam and some liquids, so it can be used as desiccant. The activated alumina can also absorb lubricant steam in polluted oxygen, hydrogen, carbon dioxide, natural gas, etc. In addition, the reactive alumina can serve as catalyst, catalyst carrier and chromatography carrier.

SHUO CHENG is excellent in processing grade A activated alumina powders with 45µm -1µm in average gain diameter in accordance with clients’ requirements. Please contact us directly if you are interested to know more about the activated alumina.
