| Abstract: | A qualitative classification algorithm for constructing large clusters of aerogel model structures is used. According to this
algorithm, aerogel is classified with polysilicas characterized by a packing of long chains of silicon-oxygen tetrahedra.
A model of the aerogel structure is suggested, according to which aerogel is described as a set of cross-linked chains forming
double or more complex ribbons. This model is in agreement with the conclusions drawn from analysis of the vibration spectra
of its components.
