Inorganic aerogels are friable and and will snap when bent or, in the case of very low density aerogels, when poked, cleaving with an irregular fracture. While aerogels may not be as glamorous as gold, they perform their tasks without peer. We’ll also see what the future holds for aerogels and if there is indeed a way to make them more cost-effective for the general public. The first aerogels were produced from silica gels.

Colorful lanthanide oxide aerogels made aerkgel epoxide-assisted gelation of metal salts image credit Lawrence Livermore National Laboratory. SEAgel is made of agar. Archived from the original on 25 May Aerogels are poor radiative insulators because infrared radiation which transfers heat passes through them.
Unsourced material may be challenged and removed. Microporous silica, microporous glass, and zeolites are common examples of aerogels.
Wikimedia Commons has media related to Aerogel. Aerogels are known as “frozen smoke” because of their ghostly blue look. The air has little room to move, inhibiting both convection and gas-phase conduction. This said, due to their low densities and length-scale effects arising from having nanostructured features, aerogels often exhibit many dramatically enhanced materials properties over adrogel non-aerogel form of the same substance for example, significant increases in surface area and catalytic activitywhile frequently also exhibiting reductions in other materials properties such as mechanical strength.

Silica aerogel is the most common type of aerogel, and the most extensively studied and used. Furthermore, iron oxide aerogels are just barely translucent and can be either rust-colored or yellow.

The hydroxyl groups can cause a strong reaction when the aerogel is placed in water, causing it to catastrophically dissolve in the water.
Many aerogels boast a combination of impressive materials properties that no other materials possess simultaneously.
Depending on the density, carbon aerogels may be electrically conductive, making composite aerogel paper useful for electrodes in capacitors or deionization electrodes. Nicknames include frozen smoke solid smokesolid airsolid aeogelblue smoke owing to its translucent nature and the way light scatters in the material.

The slight color it does have is due to Rayleigh scattering of the shorter wavelengths of visible light by the nano-sized dendritic structure. There is also an interactive properties database where you can compare the physical properties of different types of aerogels side-by-side. Archived from the original on 23 May Silica aerogel is an especially good insulator because silica is also a poor conductor of heat; a metallic or carbon aerogel, on the other hand, would be less effective.
A class of polymer-crosslinked inorganic aerogels called x-aerogels are such materials and can even be made flexible like rubber in addition to being aeroel robust see Flavors of Aerogels. Lawrence Berkeley National Laboratory.
What is Aerogel?
First Prize for Weird: It is silica -based and can be derived from silica gel or by a modified Stober process. In gas adsorption, nitrogen at its boiling point is adsorbed into the aerogel sample.

For comparison, typical wall insulation is 13 US customary or 2. Aerogels are produced by extracting the liquid component of a gel through supercritical drying.
