Characteristic
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.
Chemical formula:NaAlO2
Molar mass:81.97 g/mol
Appearance:white powder (sometimes light-yellowish)
hygroscopic/ when dissolved in water a colloidal black solution is formed
Odor:odorless
Density:1.5 g/cm3
Melting point:1,650 °C (3,000 °F; 1,920 K)
Solubility in water:highly soluble
Solubility:Insoluble in alcohol
Refractive index (nD):1.566
Application
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 solutions are intermediates in the production of zeolites.
