  • A gel with the liquid replaced with a gas
  • Tends to be ultralight, very insulative to convective and conducttive heat (not radiative however)


Produced from sodium silicate [1], which is in turn produced from sand and soda (caustic). To get gel, sodium silicate is acidified [2]. Silica aerogel is produced from silica gel. [3]. Thus, the starting materials cost for all starting materials is standard (<$1/lb), and the feedstocks are abundant. This is OSE Spec as a potential next generation insulation material.


  • Starting to be used in house insulation? [4]

Used For

  • Many, many things
  • Insulation
  • Catalysts
  • Optics
  • Chemical Absorbant (For spill cleanups etc)
  • Electronics (Supercapacitors)
  • High Tech/Scientific Research Use Cases
  • Aircraft (Lighter internal structure, electric deicing)
