| SODIUM ALUMINUM OXIDE Usage And Synthesis |
| Chemical Properties | Sodium aluminate is a white crystalline solid or solution. |
| Uses | 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. |
| Uses | Printing on fabrics; manufacture of lake colors; sizing paper; manufacture of milk-glass, soap; hardening building stones; water softener. |
| Flammability and Explosibility | Nonflammable |
| Potential Exposure | Used in water and waste treatment; papermaking industry; in printing on fabrics; in the manufacture of pigments, milk glass, and soap; hardening building stone; sizing paper; as a water softener. |
| Shipping | UN2812 Sodium aluminate, solid, Hazard class: 8; Labels: 8-Corrosive material. UN1819 Sodium aluminate, solution, Hazard class: 8; Labels: 8-Corrosive material. |
| Incompatibilities | The aqueous solution is a strong base. Reacts violently with acid. Incompatible with organic anhydrides; isocyanates, alkylene oxides; epichlorohydrin, aldehydes, alcohols, glycols, caprolactum, chlorocarbons. Corrosive to metals; attacks copper, tin, aluminum, and zinc. |
