The porous structure of this substance makes it a powerful desiccant and it holds the record for having the greatest amount of thermal insulation of any known material.
Materials of this type made from carbon reflect only 0.3 percent of radiation in the infrared spectrum making them useful solar heat collectors and superfluid helium-3 is often suspended within this type of substance in order to create anisotropic superfluids.Â A variety of this substance made from alumina are being used to capture cosmic debris in NASA's Stardust experiment. This material was first created in 1931 by(*) Samuel Kestler by increasing temperature and dropping pressure to evacuate fluids in a process called supercritical drying. The porous structure of this substance makes it a powerful desiccant and it holds the record for having the greatest amount of thermal insulation of any known material. It is often referred to as solid smoke. For 10 points, identify this type of material, a suspension consisting of a solid containing more than ninety percent air by volume.
