Sodium aluminate is an important commercial inorganic chemical. Pure sodium aluminate (anhydrous) is a white crystalline solid having a formula variously given as NaAlO2, NaAl(OH)4 (hydrated), Na2O·Al2O3, or Na2Al2O4. With the CAS NO. 1302-42-7, it is also called Aluminate (AlO21-), sodium; Aluminate (AlO21-), sodium; aluminate(alo2(1-)),sodium; aluminate(alo21-),sodium; Aluminate,sodium; aluminumsodiumoxide(al2na2o4); aluminumsodiumoxide(alnao2). Sodium aluminate is an important commercial inorganic chemical. It works as an effective source of aluminium hydroxide for many industrial and technical applications.
Preparation of Sodium aluminate: Sodium aluminate is manufactured by the dissolution of- aluminium hydroxide in a caustic soda (NaOH) solution. Aluminium hydroxide (gibbsite) can be dissolved in 20–25% aqueous NaOH solution at a temperature near the boiling point.
Sodium aluminate is also formed by the action of sodium hydroxide on elemental aluminium which is an amphoteric metal. The reaction is highly exothermic once established and is accompanied by the rapid evolution of hydrogen gas. The reaction is sometimes written as:
2 Al + 2 NaOH + 2 H2O → 2 NaAlO2 + 3 H2
Uses of Sodium aluminate: 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.
