Talk:Hydrated silica

Flame retardant?
I don't understand what that bit means and we need a ref. IceDragon64 (talk) 20:52, 14 September 2009 (UTC)

Duplicate page?
The silica gel page claims that hydrated silica is just a form of silica gel. Should this page be taken down and instead redirect to Silica gel?

 * I don't know. I created the page because Hydrated silica is a listed ingredient of toothpaste.  As I understood it, Silica Gel is a certain form of Hydrated Silica and is NOT the form used in toothpaste and NOT what you would call the material opals are made out of, in other words, it is other way round-  silica gel is just a form of hydrated silica and if anything, it should redirect here, but I am no chemist!

 * I'm pretty sure there's a difference between hydrated silica and silica gel- my understanding is that in hydrated silica (as with other hydrated minerals) the water molecules are incorporated directly into the crystal itself, forming bonds with the Silicon and Oxygen and making one cohesive solid, while in a gel, there is a distinct barrier between the solid part (silica) and the liquid part (water). Hydrated silica is not a gel, and silica gel isn't a hydrated mineral in the technical sense - Ramzuiv (talk) 01:12, 16 February 2020 (UTC)

Microcrystalline quartz (Highest crystallinity) ?
Under "Nature" it describes microcrystalline quartz as a form of Hydrated Silica. It is not hydrated, it is silica. I don't understand what this chart is supposed to tell us, but it makes no sense to me. IceDragon64 (talk) 23:47, 29 September 2023 (UTC)
