Global Info Reports Aerogels - The Strong but Lightweight Material | Page 3

Basically an Aerogel is the low-density, dry, strong and porous system of the gel (the piece
of the gel that provides the gel its solid cohesiveness) segregated wholly from the fluid
segment of the gel (the part which builds up the majority of the gel volume). The aerogels
are characterized as open- porous (i.e. the gas in the structure of aerogel isn't caught in the
strong pockets) and also have pores ranging between <1 to 100 nanometers (billionths of a
meter) in distance across and more often than not <20 nm.
