Sodium Aluminate
Sodium Aluminate Introduction
Sodium Aluminate is an inorganic chemical that is used 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, NaAl(OH)4, Na2O·Al2O3, or Na2Al2O4. Commercial Sodium Aluminate is available as a solution or a solid.
Is Sodium Aluminate toxic?
Odorless white powdered solid. Toxic by ingestion and corrosive to tissue. Used in water purification.
Uses
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.
