Aerogel, a miraculous material that can change the world
Aerogel is unlike the traditional notion of "gel." It is a solid material with a nanostructured porous network. Invented by American scientist Kistler S. in 1931, it is often referred to as "blue smoke" or "frozen smoke" due to its ethereal, misty blue appearance, and it holds an impressive record of setting 15 Guinness World Records.
The Characteristics of Aerogel

The density is 3.55 kg/m³, which is only 2.75 times the density of air.
High Porosity
The porosity is >90%
Super Hydrophobic
Hydrophobic rate >90%
Low Thermal Conductivity
Thermal conductivity lower than air :≤0.016W/(m.k)
High Surface Area
600-800㎡/g
Nanoporous Structure
1-100nm
Types of Aerogel
Aerogels come in various types, including silicon-based, carbon-based, sulfur-based, metal oxide-based, and metal-based aerogels. Among these, silica aerogel (SiO₂ aerogel) is one of the most widely used and industrially developed forms of aerogel. Both domestic and international efforts in aerogel industrialization primarily revolve around the insulation applications of silica aerogels.
Aerogels possess unparalleled insulation capabilities that cannot be matched by other materials.
Among the numerous properties of aerogels, their insulation performance is the most mature and widely applied. Aerogels are currently known as one of the most effective solid materials for insulation. The unique structure of aerogels can impede all avenues of heat transfer, including thermal conduction, convection, and radiation, allowing aerogels to achieve unparalleled insulation performance compared to other materials.
The Insulation Principle of Aerogels
The "Zero convection" effect
Aerogel has a smaller aperture (20-50nm) than the average for air
Free path (70nm) so the internal air can not circulate freely.
The "Infinite shielding plate"
The network structure of aerogels results in an "infinite thermal insulating plate" effect, which has a shielding impact on thermal radiation.
The "Infinite long pathway"
Aerogels extends the thermal conduction pathway indefinitely through their network-like structure, making it challenging for heat to conduct at the gas-solid interface.
Aerogel, a widely recognized new material worldwide
Aerogel exhibits numerous remarkable properties in the fields of thermics, optics, electronics, mechanics, acoustics, and more. It is often referred to as a "magical material that can change the world" and is considered one of the prominent new materials of the 21st century. It holds immense dual-use value in both military and civilian applications and has been included in national strategic emerging industries.
