water glass liquid sodium silicate with competitive price
1.Description:
Sodium silicate is the common name for a compound sodium metasilicate, Na2SiO3, also known as water glass or liquid glass.sodium silicate is white solid that is readily soluble in water ,producing an alkyl
soultion.it is one of a number or related compounds which includes sodium orthosilicate and sodium
pyrosilicate all are glassy ,colorless(transparent) and dissolve in water ,sodium silicate is stable in neutral
and alkaline solutions and in acidic solutions ,the silications reacts with hydrogen ions to form silicic acid
,which when heated and roasted form of Silica Gel,A hard ,glassy substance
