- Aerogel - Wikipedia
Aerogels are a class of synthetic porous ultralight material derived from a gel, in which the liquid component for the gel has been replaced with a gas, without significant collapse of the gel structure [3] The result is a solid with extremely low density [4] and extremely low thermal conductivity Aerogels can be made from a variety of

Aerogels are among the lightest solid materials known to man They are created by combining a polymer with a solvent to form a gel, and then removing the liquid from the gel and replacing it with air Aerogels are extremely porous and very low in density They are solid to the touch

What is Aerogel? The most common type of aerogel, silica aerogel, is derived from a sol gel reaction in which the liquid filled pores have been replaced with gas This results in an extremely low-density solid that can be imparted with several remarkable properties such as hydrophobicity

Alcogel is an amorphous silica gel with alcohol inside its pores Simply evaporating the alcohol out of the silica gel structure would cause the structure to contract, much like a wet sponge will deform when left on a counter to dry Instead of relying just on evaporation, the gel has to be supercritically dried Here's what it takes:

An aerogel is an open-celled, mesoporous, solid foam that is composed of a network of interconnected nanostructures and that exhibits a porosity (non-solid volume) of no less than 50% The term “mesoporous” refers to a material that contains pores ranging from 2 to 50 nm in diameter

Aerogel, a remarkable material with extraordinary properties, is often referred to as “frozen smoke” or “blue smoke” due to its translucent appearance and low density It is a unique form of solid material that is created by removing the liquid component from a gel through a process called supercritical drying

An aerogel is an open-celled, mesoporous, solid foam composed of a network of interconnected structures that exhibits a porosity (non-solid volume) of no less than 50% Historically, the most researched type of aerogel has been the holographic-looking “blue” silica type Today, aerogels of numerous different substances can be prepared

‘Aerogel’ is not a specific mineral or material with a set chemical formula - rather, the term is used to encompass all materials with a specific geometrical structure This structure is an extremely porous, solid foam, with high connectivity between branched structures a few nanometres across
