Synthesis and Structure of Borate Based Aerogelsnormally alcohol) is replaced by a non-condensed gas with little or no associated shrinkage. Aerogel density therefore generally scales with the volume fraction (concentration) of condensed species in the original gel.

Thermal Transport in Porous Superinsulationsrting steel or aluminum walls, generally employed in cryogenic storage tanks, can be substituted by thin and flat steel and plastic envelopes. For gel systems, even transparent glass panes can be used as protective covers. Thermal superinsulations can be used in many technical systems:

Thermal Conductivity of Granular SiO2 Aerogelof k ≈ 0.5 W/(m. ·K) and thus extremely low compared to conventional translucent thermal insulations. Aerogel could be employed in modified house or Trombe wall systems, for direct gain applications in greenhouses, indoor swimming-pools etc., or for long-term storage of solar energy in saltless solar ponds.

Radiative Heat Transfer in Silica Aerogel total heat flux are precisely known. This, however, implies a detailed experimental and theoretical investigation of the radiative heat transfer as well as the precise calorimetric measurement of the total thermal transport in aerogel.
