Abstract

Aerogels hold 15 titles in the Guinness World Records, i.e. more than any other material. Sometimes aerogels are called “frozen smoke” and derived from aluminum, chromium, tin oxide or carbon in the process of supercritical drying. The composition of aerogels is 99.8% air, which makes it translucent. Aerogels demonstrate properties that make them the most extraordinary insulating materials known. If you have a shield made of aerogels, it will protect you from fire, as well as it will save you from cold. Using this material an insulated and worm dome could be built on the Moon. Aerogels have an incredible surface area of internal fractal structures, i.e. an aerogels cube with an edge of one inch has an internal area equivalent to a football field. The article deals with the concept of aerogels, the most common aerogels, and fields of their application.
