aerogelejä
Aerogels are a class of synthetic porous ultralight materials derived from a gel, in which the liquid component of the gel has been replaced by a gas. The result is a solid with extremely low density and low thermal conductivity. Aerogels are often referred to as "frozen smoke," "solid air," or "blue smoke," due to their ethereal appearance and low density.
The first aerogels were produced in the 1930s by Samuel Stephens Kistler. They are typically made from
Aerogels possess remarkable properties. Their density can be as low as 0.0011 g/cm³, making them lighter than
Current and potential applications for aerogels are diverse. They are used in high-performance insulation for spacecraft,
