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, Na2O·Al2O3, or Na2Al2O4.
We supply commercial sodium aluminate as a solution or a solid.
Solid sodium aluminate as composition of 45-50 wt. % Na2O and 50-55 wt. % Al2O3.
Sodium aluminate is used as source of alumina and sodium oxide in the production of zeolites, adsorbents, molecular sieves and catalysts.
In construction technology, sodium aluminate is employed to accelerate the solidification of concrete, mainly when working during frosty periods.
