Description

 

Sodium aluminate is an important commercial inorganic chemical. It works as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate (anhydrous) is a white crystalline solid having a formula variously given as NaAlO2, Na2O · Al2O3, or Na2Al2O4. Commercial sodium aluminate is available as a solution or a solid.In water treatment it is used as an adjunct to water softening systems, as a coagulant aid to improve flocculation, and for removing dissolved silica and phosphates.In construction technology, sodium aluminate is employed to accelerate the solidification of concrete, mainly when working during frost.Sodium aluminate is also used in the paper industry, for fire brick production, alumina production and so forth.Sodium aluminate sol
