Aerogel is a synthetic material derived from gel in which the liquid in the gel has been replaced with a gas. It was invented by Samuel Stephens Kistler in 1931.
Aerogels are a diverse class of materials which can be composed of many different substances. The lowest density aerogels that have ever been produced were silica aerogels about 0.0011 g/cm3 in density, making them about 2002 times lower density than fused silica, a high-purity form of glass which has a density of 2.203 g/cm3. This is the most useful direct comparison since the composition of silica aerogels and fused silica are the most alike. In comparison to common soda-lime glass, which contains elements other than silicon, oxygen, and hydrogen and has a density of about 2.52 g/cm3, these ultralow density aerogels are 2291 times lower density. Typically, silica aerogels and non-silica aerogels range from about 0.01 g/cm3 to 0.5 g/cm3 in density, so a useful range to report would be "between 5 to 250 times lower in density than common soda-lime glass, and as low as 2290 times for the lightest aerogels ever produced".
Earth's lightest materials typically consist of substances such as aerogels, silica aerogels, and composite foams. These materials are specifically engineered to be lightweight and have low density with exceptional strength-to-weight ratios. They find applications in various industries such as aerospace, automotive, and construction due to their unique properties.
Aerogels are a class of extremely lightweight materials that have air suspended in some solid material, in which the ratio of air to solid is extremely high. The usual kind of materials that we see in the "bluish" aerogel is made of silica. Aerogels are very heat-resistant, and are used by scientists in the aerospace industry to make lightweight insulators, or as a material that is used to catch space dust.
Aerogels - but this is an artificial compound. Among naturally occurring metals, Lithium (Li).
Carbon fiber and Kevlar are both very tough and strong but the strongest and lightest material on the face of the earth is Aerogels. Aerogels are made of 90%-99% air and usually silica but can be any material It has tensile strengths of 16 KPa or higher. It is an extremal good insulator Aspen Aerogels has hiking gear that they are selling.
The most common use for Aerogel is for thermal insulation. Silica Aerogel has been used to help insulate the Mars Rover and protected all the wiring from the extreme temperatures it faces in outer space.
Aerogels, such as silica aerogel and graphene aerogel, are some of the lightest materials on Earth. They are composed of a highly porous structure that makes them extremely lightweight while also possessing unique thermal insulation properties.
Aerogel is a manufactured material with the lowest known density of any solid. It is derived from a gel in which the liquid component of the gel has been replaced with a gas. The result is an extremely low-density solid with several remarkable properties, most notably its effectiveness as a thermal insulator and its extremely low density. It is nicknamed frozen smoke, solid smoke or blue smoke due to its translucent nature and the way light scatters in the material; however, it feels like expanded polystyrene (styrofoam) to the touch.Aerogels are produced by extracting the liquid component of a gel through supercritical drying. This allows the liquid to be slowly drawn off without causing the solid matrix in the gel to collapse from capillary action, as would happen with conventional evaporation. The first aerogels were produced from silica gels. Kistler's later work involved aerogels based on alumina, chromia and tin oxide. Carbon aerogels were first developed in the late 1980s.

The common range of densities for solids is typically between 1 g/cm^3 and 20 g/cm^3. However, certain materials can have densities outside of this range, such as aerogels with densities less than 0.1 g/cm^3 or osmium with a density of around 22.59 g/cm^3.
