An aerogel material can range from 50% to 99.98% air by volume, but in practice most aerogels exhibit somewhere between 90 and 99.8% porosity. [12] Aerogels have a porous solid network that contains air pockets, with the air pockets taking up the majority of space within the material. [13]
SEAgel (Safe Emulsion Agar gel) is one of a class of high-tech foam materials known as aerogels.It is an excellent thermal insulator and among the least dense solids known. . SEAgel was invented by Robert Morrison at the Lawrence Livermore National Laboratory in 19
Boron nitride aerogel is an aerogel made of highly porous BN. It typically consists of a mixture of deformed BN nanotubes and nanosheets . It can have a density as low as 0.6 mg/cm 3 and a specific surface area as high as 1050 m 2 /g, and therefore has potential applications as an absorbent , catalyst support and gas storage medium.

Aerographene or graphene aerogel is the least dense solid known to exist, at 160 g/m 3 (0.0100 lb/cu ft; 0.16 mg/cm 3; 4.3 oz/cu yd). [1] The material reportedly can be produced at the scale of cubic meters.
Aerogel is a low-density solid-state material derived from gel in which the liquid component of the gel has been replaced with gas. The result is an extremely low density solid with several remarkable properties, most notably its effectiveness as a thermal insulator. It is also very strong structurally, able to hold over 2000 times its own weight.
Metal chalcogenide aerogels can be prepared from thiolysis [5] or nanoparticle condensation [6] [7] and contain crystalline nanoparticles in the structure. [7] The synthetic method can be extended to many thioanions, including tetrathiomolybdate-based chalcogels. [8] Different metal ions have been used as linkers Co 2+, Ni 2+, Pb 2+, Cd 2+, Bi ...
