Activated Alumina Balls Description

Surface area are in the range 345-415 m²/gm . Because it has a higher capacity for water than Silica Gel at elevated temperatures it is mainly used as a desiccant for warm gases including air. In many commercial applications zeolitic materials have now replaced it.
