The possibility of applying of acoustic methods for the monitoring of sol-gel processes

Models simulating the propagation of acoustic waves in the
successive stages of the gelation process are presented. The early stage of
gelation has been considered with scattering theory for very low concentrations
of suspensions. The system may be simulated by the line of the independent
Maxwell elements. When concentration of the suspension increases, the
interaction of the particles can be presented by an acoustic model, which
consist of a chain of coupled Maxwell elements. After the gelation point, the
system becomes rigid, and three dimensional tensoral fields distribution of
stress and strain was used.
