Chemically stable,flame-resisting.Insoluble in any solvent except strong alkali or hydroelectric acid. In comparison with fine-pored silica gel ,the adsorption capacity of silica alumina gel is quite the same when used at low relative humidity ,(e.g.RH=10%,RH=20%),while its adsorption capacity at high humidity is 6-10%higher than that of fine-ported silica gel. Its thermal stability is over 150ºC higher than that of fine-pored silica gel (200 ºC).Ideally suited for use as absorbent and variable-temperature absorbent.
