Sodium aluminum oxide (Al2O3.Na2O)-Crystalline

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 having a formula variously given as NaAlO2, NaAl(OH)4 (hydrated),Na2O·Al2O3, or Na2Al2O4.

Application




Sodium aluminum oxide is used in the isomerization of alkene and isomerization of amines. It is also used in water treatment as an adjunct and as a coagulant aid to flocculation. It is involved in the removal of silica and phosphates from waste water. It is employed to accelerate concrete solidification. It finds application in the paper industry and fire brick production. It acts as an intermediate in the production of zeolites.
