Aerogels Technology

The worlds lightest, That is least dense, solid. Aerogel was first created by Samuel Stephens Kistler in 1931.
Aerogel is a synthetic porous ultralight material derived from a gel, in which the liquid component for the gel has been replaced with a gas. The result is  solid with  extremely low density &   extremely low thermal conductivity.

How it is made

Aerogels are produced by extracting the liquid components of a gel through supercritical drying. This allows the liquid to be slowly dried off without causing the solid matrix in the gel. Aerogel is not a single material with a set chemical formula; instead, the term is used to group all materials with a certain geometric structure. For more details Click Here

Advantages

  • Aerogel is a material that is 99.8% air. Aerogels have a porous solid network that contains air pockets. The lack of solid material allows aerogel to be almost weightless.
  • Aerogels are good thermal insulators.
  • They are good conductivity insulators
  • Aerogels are poor radiative insulators because infrared radiation passes through them.
