Description

White Powder Sodium Metasilicate Anhydrous and Pentahydrate for Detergent Powder
 

~Commodity Name : Sodium Metasilicate (Anhydrous / Pentahydrate)
Structural formula: Na2SiO3•nH2O (n=0,5)
CAS No. : ********0

Properties :

Sodium metasilicate is an inorganic white powder, non-toxic, tasteless and environment-safe. It is easy soluble in water, insoluble in alcohol or in acid producing an alkaline solution, very hygroscopic when reacting with CO2 and water from the air. It has the capabilities of removing scale, emulsifying, dispersing, wetting, penetrating, and also has the capability of buffering PH value.
