ALUMINA BALLS |

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