Silica aerogel

Silica aerogels are unique in chemistry and have intrigued scientists and engineers alike. They have distinct properties that are attractive in a number of technologies. Although it has been in existence since 1930, silica aerogels are still fairly new in terms of discovery and research. Aerogel's air-like qualities have been put to use for home insulation to comet catchers. With the right combination, aerogels can improve computer chips and even act as capacitors. Aerogels even have the potential of improving the environment. For these reasons, government labs such as NASA, among others, have been supporting the continued study of aerogels. The present paper discusses chemical aspects, the manufacturing process, electrical applications, advantages and disadvantages of its use.
