Aerogel is an ultra-low density material with very unique properties. It can be made from SiO₂, Al₂O₃ or other ceramics. It is the lowest density solid known to exist, yet it can support up to 4000 times its own weight (Silica Aerogels, 2007). The low density and high content of air (more than 95%) lead to its extremely low thermal conductivity. Many new products are being made that utilize the extraordinary properties of aerogel. With future research into aerogels, the applications will be able to be implemented into everyday life. Already aerogels are being made use of as energy saving insulators and comet dust particle collectors. With the increase in interest, there will be many more advancements and products that employ aerogels.
