What are the types of aerogels?
What are the types of aerogels?
Monolith, powder, and film are the three types of aerogel based on appearance. It’s called aerogel, xerogel, cryogel, or hydrogel depending on how it’s produced. On the basis of different microstructures, aerogel is graded as microporous aerogel (2 nm), mesoporous aerogel (2–50 nm), and mixed porous aerogel.
Is there a particular company that manufactures aerogel?
Aerogel Technologies, LLC is the world’s leading manufacturer of mechanically strong aerogel materials and monolithic aerogels, leading online distributor of aerogel materials, and leading provider of custom aerogel solutions.
What is aerogel good for?
Aerogels provide very effective insulation, because they are extremely porous and the pores are in the nanometer range. The nano pores aren’t visible to the human eye. The existence of these pores makes the aerogel so adept at insulating.
Why is aerogel expensive?
Aerogel preparation involves expensive precursors, chemicals, and the need for supercritical drying, making the production relatively more expensive compared to the current conventional building insulations.
Is Aspen Aerogels a good investment?

Can aerogel get wet?
Classic silica aerogels and other oxide-based aerogels are not natively waterproof but can be modified to not only be waterproof, but superhydrophobic. Mechanically strong Airloy® aerogels made by Aerogel Technologies are water-resistant with varying levels of hydrophobicity for different applications.
What is the history of aerogel?
Aerogel was first created by Samuel Stephens Kistler in 1931, as a result of a bet with Charles Learned over who could replace the liquid in “jellies” with gas without causing shrinkage. Aerogels are produced by extracting the liquid component of a gel through supercritical drying or freeze-drying.
Can you eat aerogel?
Do not eat. Although Aeroeggs are made from real eggs and in principle egg aerogels could be eaten if prepared properly, these aerogels are supercritically dried in industrial equipment that processes chemicals and that is not food grade making them not edible. Seriously don’t eat them, not even rehydrated.
