Silicon dioxide aerogel is the lightest solid material that people known currently, because it has the characteristic of nano-porous
structure(1 - 100nm) , low density(1-500kg/m3) , low permittivity(1.1-2. 5), low thermal conductivity (0.013-0.025w/(m.k) , high porosity
(80-99.8%) high specific surface area (200-1000m2/g)etc. It shows the unique properties in mechanics , acoustics, thermology, optics,it has the broad and the huge application prospect on the field of aerospace, military ,communicaions ,medicine, building materials. electronics , metallurgy ,so it was called : " the magical materials to change the world " .
The thermal insulation performance of silicon dioxide aerogel is the best in the currently , the hole size is lower than the mean free paths of air molecules which is usual atmospheric pressure , that is why the air molecules in aerogel is like static , so that avoid the convective haet transfer in the air ,the gaseous and solid heat transfer is prevented by the aerogel ' s super low bulk density and curved path of its nano-grid structure, the almost"Infinite"gap wall could reduce the heat radiation to the lowest. These three aspect play together, almost block all of the channel of heat transfer , make aerogel reached the insulation effect that the other material can not compare, even the heat conductivity is lower than 0.025W/m K, below 0.013W/m.K
