The best solution to use is the colloidal silica, LudoxTM.

They're made from silica. Why not structures from cars like that?

Aerogel is a very low density solid that can be produced with refractive index in the range from 1.002 to 1.265.

If a reversed order of running of the compounds is desired, an apolar stationary phase should be used, such as C18 functionalized silica.

Dry water actually consists of 95 percent liquid water, but the silica coating prevents the water droplets from combining and turning back into a bulk liquid.

Glass for flat glass has a higher magnesium oxide and sodium oxide content than container glass, and a lower silica, calcium oxide, and aluminium oxide content.

Generally speaking, more mafic magmas, such as those that form basalt, are hotter and less viscous than more silica rich magmas, such as those that form rhyolite.

For instance, reagent quality water must have very low levels of impurities such as sodium and chloride ions, silica, and bacteria, as well as a very high electrical resistivity.

Toothpaste typically has small particles of silica, aluminum oxide, calcium carbonate, or calcium phosphate to grind off stains formed by colored molecules that have absorbed onto the teeth from food.

The typical chemical composition of oven dried diatomaceous earth is 80 to 90 silica, with 2 to 4 alumina (attributed mostly to clay minerals) and 0.5 to 2 iron oxide.

The large scale structure of carbon nanofoam is similar to that of an aerogel, but with 1 of the density of previously produced carbon aerogels or only a few times the density of air at sea level.
