Silica aerogel is also known as "blue smoke" or "solid smoke", which is currently known to have low density and mass Light solid materials are also materials with good thermal insulation performance so far. Because of its nanoporous structure (1~100nm), low density (3~250kg/m3), low dielectric constant (1.1~2.5), low thermal conductivity Number (0.013~0.025W/(m-k)), high porosity (80~99.8%), surface area (500~1000m2/g) and other characteristics, showing uniqueness in mechanics, acoustics, thermals, optics, etc.
In terms of quality, aerogels seem to be "weak", but they are actually very durable. It can bear the equivalent of its own quality A thousand times the pressure will melt when the temperature reaches 1200 degrees Celsius. In addition, its thermal conductivity and refractive index are also very Low, insulation capacity is 39 times stronger than good glass fiber. In aerospace, chemical industry, minerals, Communication, medical, building materials, electronics, metallurgy and many other fields have extensive and huge application value, and are called "magic materials that change the world".
