This paper probes into the influences of physical property of aluminum hydroxide on the strength of active alumina in the process of active alumina production with fast dehydration method.

Alcoa is the world's leading producer and manager of primary aluminum, fabricated aluminum and alumina facilities, and is active in all major aspects of the industry.

The procedure was described, including extraction by acetone and dichloromethane, cleaning up by passing through a column made up of neutral alumina and active carbon, determination by GC with NPD.
