Abstract: The low-frequency electrical conductivity of dielectric colloids (polysterene and silica) and metallic (silver) ones in aqueous solutions shows a power-law behavior in time during the salt-induced cluster-cluster aggregation. We interpret this fact using current theories of heterogeneous dielectric systems. The fractal nature of the clusters, checked by light scattering, determines the exponent of the power law.
