Air and Water Reactions:Deliquescent. Water soluble [Handbook of Chemistry and Physics].
Reactive Group:Salts, Basic
Reactivity Profile:SODIUM SILICATE contains a variable amount of water of hydration. Rate of dissolution depends on the degree of hydration, the amount of water that is used as solvent (less soluble in large amounts of water) and the temperature (higher temperature means quicker solution). Aqueous solutions react as bases. Reacts violently with fluorine [Lewis.]
Autoignition Temperature:Not flammable (USCG, 1999)
Corrosivity:Sodium metasilicate is considered to be too corrosive to be widely used in consumer product laundering formulations.
