Resorcinol silica aerogels

Figure 23.7. Effective specific extinction of a nonopacified and opacified silica aerogel, resorcinol-formaldehyde (RE) aerogel and carbon aerogel as a function of the wavelength. Additionally, the normalized Rosseland weighting function is depicted, which shows the maximum thermal radiation for 300 K at a wavelength of 8 pm [24].

Figure 23.8. Rosseland-averaged total effective specific extinction e (T) using the spectral values (Figure 23.7) as a function of temperature of an opacified silica aerogel, resorcinol—formaldehyde (RF) aerogel and cathtm aerogeL...
