ommonly known as solid smoke, solidified smoke, born in 1931; It is a three-dimensional nano porous solid material: first it is made into a wet gel, and then the internal liquid is replaced with gas to keep the nano skeleton from collapsing.
The porosity is 80% to 99.8%, and the vast majority of the volume is air. At present, it has been used as high-temperature insulation material, acoustic impedance coupling material, catalytic preparation, adsorbent, filtration material, etc.
