Activated Alumina is an aluminium oxide that is highly porous and exhibits tremendous surface area. It 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 . In many commercial applications zeolitic materials have now replaced it.
