Sodium Aluminate Properties

Sodium Aluminate



Sodium aluminate is used in water treatment 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.
