Aerogel is a kind of thermal insulation material that can be used in space suits. The reason why astronauts can withstand the high
temperature of 800℃ and the low temperature of -130℃ is because of the existence of aerogel.
Are you still choosing traditional fabrics for your warm clothes?Take a look at this new aerogel fabric, one of the world's
lighter, more insulating materials.
Heat transfer in solids: aerogel (amorphous silica) particles, the main component of aerogel felt, are smaller in molecular
diameter than cigarette smoke (about 10nm), and thus have a very small sectional area through which the particles can pass heat,
and thus have very low heat transfer compared with ordinary thermal insulation materials.
