It is nicknamed "frozen smoke" and "blue smoke", due to its semi-transparent nature and the way light scatters in the material; however, it feels like Styrofoam to the touch.
Aerogel is not like conventional foams, but is a special material with porosity on a micron scale. It is composed of individual features only a few nanometers in size. Aerogels are 99.8% air.
Aerogels are remarkable thermal insulators. Their high surface areas also make them useful in manufacturing sensors and filters Aerogels are currently used in many industries and applications including:
Space
Transportation
Construction
Appliances
Outdoor gear
Catalysts
Sensors
Air/Water Purification
