SODIUM SILICATE
ca: SILICAT SÒDIC
es: SILICATO SÓDICO
Sodium silicate is the common name for a compound sodium metasilicate, Na2SiO3, also known as water glass or liquid glass. It is available in aqueous solution and in solid form and is used in cements, passive fire protection, refractories, textile and lumber processing, and automobiles. Sodium carbonate and silicon dioxide react when molten to form sodium silicate and carbon dioxide. Na2CO3+SiO2→Na2SiO3+CO2
In ceramics it is a powerful alkaline flux. See: Wikipedia
