Aerogel like materials

Producing aerogel-like materials without supercritical drying at all preparation of inorganic—organic hybrid materials. ... 

Ambient Preparations. Economic and safely considerations have provided a strong motivation for the development of techniques that can produce aerogel-like materials at ambient conditions, i.e., without supercritical drying. The strategy is to minimize the deleterious effect of capillary pressure which is given by ... 

In real life. Si alkoxides are often available as complexes in solution in their parent alcohol and are typically polymerized to a smaller or larger extent. Even if some monolithic but quite dense aerogel-like materials can be synthesized through ultrasonic-assisted solventless sol-gel routes (Chap. 20) [31, 32], their polymerization is mostly carried out in an organic solvent through simultaneous hydrolysis (2.2) and po ycondensation of water (2.3) and alcohol (2.4) so that water becomes a reactant added in controlled proportion to drive the hydrolysis reaction (2.2).

These special xerogels belong to a family of aerogel like materials. However the pore volume of the aerogel like materials is comparatively lower than that of conventional aerogels (Land, 2003).
