Silica Aerogels
Silica aerogels are a new material composed of silicon dioxide (SiO2) nanostructures made of silica particles tens of nanometers in size, loosely interwoven like a nonwoven fabric, and are the lightest among all solid materials and possess excellent ultra-thermal insulation and non flammability properties.
