sodiumaluminate

Sodium aluminate is an inorganic chemical compound with the formula NaAlO2. It is a white, amorphous solid that is highly soluble in water. Sodium aluminate is formed when aluminum oxide reacts with sodium hydroxide. It can also be produced by heating aluminum metal with sodium hydroxide.

In aqueous solution, sodium aluminate exists as various aluminate ions, such as [Al(OH)4]− and [Al(OH)3(H2O)]−, depending on the pH. It is a strong base and reacts with acids to form aluminum hydroxide and a sodium salt.

Sodium aluminate has a variety of industrial applications. It is used as a flocculant in water treatment to remove suspended solids and impurities. It is also employed in the production of paper, textiles, and ceramics. In construction, it acts as an accelerator for cement. Furthermore, it finds use in the manufacturing of zeolites and other aluminum-containing materials. In some applications, it is used as a source of aluminum oxide.
