Sodium aluminate (NaAlO₂) is an inorganic ceramic compound formed from the reaction of sodium oxide and aluminum oxide, commonly encountered as a white crystalline solid or in aqueous solution. It is primarily used in water treatment and purification processes, where it acts as a coagulant aid and pH buffer, and also serves as a raw material in the production of alumina and aluminum compounds for industrial applications. Engineers select sodium aluminate for its ability to modify water chemistry and improve clarification efficiency in municipal and industrial water systems, though its use is often application-specific rather than structural.
