Aerogel
chemical formula: N/A (proprietary)
( granular )
Developed by NASA, Aerogel is the lightest and lowest-density solid known to exist. It also holds the World records for being the best insulator and lowest density solid. Aerogel is composed of amorphous Silicon Dioxide, and 99.8% Air.
 Aerogel negates just about any kind of energy transfer - thermal, electrical or acoustic. Aerogel's density is just 3 milligrams per cubic centimeter (it weighs only three times that of air). Its melting point is 2,200 degrees F (1,200 degrees C). Click Here for a close-up of the particle size. Due to its light weight, it is sold by volume and not weight ( the quantity of Aerogel shown in the image above is 100cc ).
See our Aerogel page for larger samples of Aerogel and additional information on this amazing material.
