2. Sodium silicate - Wikipedia

   en.wikipedia.org/wiki/Sodium_silicate

   Sodium silicate solutions can also be used as a spin-on adhesive layer to bond glass to glass [21] or a silicon dioxide–covered silicon wafer to one another. [22] Sodium silicate glass-to-glass bonding has the advantage that it is a low-temperature bonding technique, as opposed to fusion bonding. [21]

3. Sand casting - Wikipedia

   en.wikipedia.org/wiki/Sand_casting

   Water glass ( sodium silicate [Na 2 SiO 3 or (Na 2 O)(SiO 2)] ) is a high strength binder used with silica molding sand both for cores and molds. [22]: 69–70 To cure a mixture of finely ground sand (e.g. by using a sand muller) and 3 to 4% of sodium silicate the binder, carbon dioxide (CO 2) gas is used.

4. Core (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Core_(manufacturing)

   For example, a cold-box sand casting core binder is sodium silicate which hardens on exposure to carbon dioxide. [5] Special binders are used in air-set sands to produce core at room temperature. These sands do not require a gas catalyst because organic binders and a curing catalyst are mixed together in the sand which initiates the curing process.

5. Can I use sand as cat litter? We asked a vet to find out! - AOL

   www.aol.com/sand-cat-litter-asked-vet-120000565.html

   Cons: 1. Limited absorbency Sand is not as absorbent as the best cat litter, which can lead to excess moisture in the litter box.. 2. Poor odor control Sand does little to neutralize odors ...

6. Silicate mineral paint - Wikipedia

   en.wikipedia.org/wiki/Silicate_mineral_paint

   Silicate mineral paints or mineral colors are paint coats with mineral binding agents. Two relevant mineral binders play a role in the field of colors: Lime and silicate. Under influence of carbon dioxide, lime-based binders carbonate and water silicate-based binders solidify. Together they form calcium silicate hydrates. [1]

7. Silica gel - Wikipedia

   en.wikipedia.org/wiki/Silica_gel

   An aqueous solution of sodium silicate is acidified to produce a gelatinous precipitate that is washed, then dehydrated to produce colorless silica gel. [6] When a visible indication of the moisture content of the silica gel is required, ammonium tetrachlorocobaltate(II) (NH 4) 2 [CoCl 4] or cobalt(II) chloride CoCl 2 is added. [6]

9. Colloidal silica - Wikipedia

   en.wikipedia.org/wiki/Colloidal_silica

   The subunits of colloidal silica particles are typically in the range of 1 to 5 nm. Whether or not these subunits are joined depends on the conditions of polymerization. Initial acidification of a water-glass (sodium silicate) solution yields Si(OH) 4. If the pH is reduced below 7 or if salt is added, then the units tend to fuse together in chains.
