What are some uses for Sodium Silicate?
Metal repair Sodium silicate is used, along with magnesium silicate, in muffler repair and fitting paste. When dissolved in water, both sodium silicate, and magnesium silicate form a thick paste that is easy to apply. When the exhaust system of an internal combustion engine heats up to its operating temperature, the heat drives out all of the excess water from the paste. The silicate compounds that are left over have glass-like properties, making a somewhat permanent, brittle repair. [edit] Automotive repair Sodium silicate can be used to seal leaks at the head gasket. A common use is when an alloy cylinder head motor is left sitting for extended periods or the coolant is not changed at proper intervals, electrolysis can “eat out” sections of the head causing the gasket to fail. Rather than pull the head, a jar of “liquid glass” is poured into the radiator and allowed to circulate. The waterglass is injected via the radiator water into the hotspot at the motor. This technique works bec
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 art. Sodium carbonate and silicon dioxide react when molten to form sodium silicate and carbon dioxide[1]: Na2CO3 + SiO2 → Na2SiO3 + CO2 Anhydrous sodium silicate contains a chain polymeric anion composed of corner shared {SiO4} tetrahedra, and not a discrete SiO32− ion[1]. In addition to the anhydrous form there are a number of hydrates with the formulae Na2SiO3.nH2O (where n= 5, 6, 8, 9) which contain the discrete approximately tetrahedral anion SiO2(OH)22− with water of hydration e.g. the commercially available sodium silicate pentahydrate, Na2SiO3.5H2O is formulated Na2SiO2(OH)2.4H2O and the nonahydrate, Na2SiO3.9H2O is formulated Na2SiO2(OH)2.8H2O .[2 Properties Sodium silicate is a white solid that is readily

This technique works because at 210–220 °F the sodium silicate loses water molecules to form a very powerful sealant that will not re-melt below 1500 °F. Sources: http://en.wikipedia.
