Figure 21.24 shows a typical isotherm for an aerogel with a density of about 200 kg/m. The arrows indicate the adsorption and desorption branches of the isotherm in the range of capillary condensation. According to the lUPAC classification scheme... 

Table 7.1 shows the classification, sample distribution, and their physical properties for each granule size. Figure 7.4 shows how the silica aerogel granules are prepared for the experiment. First, the acoustics absorption of an appropriate thin porous ply is evaluated. Then, silica aerogel granules of various sizes are filled in the impedance mbe to the depths of 10 and 15 mm covered with a layer of porous ply held...
