Aerogel is a synthetic porous ultralight material derived from a gel, in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density and low thermal conductivity. Nicknames include frozen smoke, solid smoke, solid air, or blue smoke owing to its translucent nature and the way light scatters ...

The lightest solid material known, with a density only three times that of air. Its remarkable properties are being exploited on space missions, including some that are of relevance to astrobiology. Aerogel was discovered in 1931 by Steven Kistler, a Stanford University researcher, and is sometime...

aerogel 1. A highly porous solid formed from a gel, such as silica gel, in which the liquid is replaced with a gas. 2. A highly porous solid formed by replacement of liquid in a gel with a gas so that there is little shrinkage. 3. A gel formed by the dispersion of air in a solidified matrix; a solid foam, as Styrofoam. 4. A porous solid formed b...

Light, transparent, highly porous material composed of more than 90% air. Such materials are formed from silica, metal oxides, and organic chemicals, and are produced by drying gels – networks of linked molecules suspended in a liquid – so that air fills the spaces previously occupied by the liquid. They are excellent heat insulators ...
