Abstract
The small-angle scattering from xerogels represents a superposition of two components: the scattering from large irregularities—the aggregates of particles, which predominates at the smallest angles, and the scattering from smaller irregularities—pores, which predominates at the comparatively large angles. These contributions to scattering are subdivided, and the parameters of the porous structure are determined. The found values of parameters agree with those obtained by adsorption and other methods. The study of the mass-transfer processes showed that their main regularities are similar to those earlier observed for carbon adsorbents; however, in xerogels these processes proceed much faster.
