ACTIVATED ALUMINA BALLS |
Activated Alumina is an aluminium oxide that is highly
porous and exhibits tremendous surface area. Activated Alumina
is resistant to thermal Shock and abrasion and will not
shrink, swell, soften nor disintegrate when immersed in
water.
Surface area are in the range 345-415 M2g.
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.
