Commodity:Sodium Aluminate Other names:Aluminium sodium dioxide; SodiumaluminatecaHO; dialuminum; oxygen(-2) anion; sodiooxysodium Molecular formula: NaAlO2 CAS No.: 1302-42-7 Property: colorless, odorless, tasteless, strongly alkaline. Solid type: white powder or granules, hygroscopic, readily soluble in water. The aqueous solution may absorb CO2 and form aluminum hydroxide precipitate. Addition of NaOH is required to increase stability. Liquid type: transparent slurry, stable during storage life. Prolonged stay of diluted aqueous solution may cause aluminum hydroxide precipitate. Use: In the construction process, it can be used as leaking stoppage agent combined with the sodium silicate. In paper-making, this product can mix with aluminum sulfate to be a good filling agent. In water treatment, it can be used as additive of purifier.
