Hogyan jön létre az Airgel?

      Aerogels are usually prepared by the sol-gel method and supercritical drying. In the sol-gel process, by controlling the hydrolysis and condensation reaction conditions of the solution, nanoclusters of different structures are formed in the solution, the clusters adhere to each other to form a gel, and the solid-liquid skeleton around the gel is filled with chemical reactions. remaining liquid reagents.

    Aerogel is named by S. Kistler. Since he successfully prepared silica aerogel by supercritical drying method, he defines aerogel as: the material obtained by supercritical drying of wet gel, which is called Aerogel. These properties of aerogels have a variety of uses in space exploration. Aerogel materials are used on the Russian "Mir" space station and the American "Mars Pathfinder" probe.
