The aggregation kinetics of basic yttrium carbonate particles in aqueous solution have been studied using dynamic light-scattering techniques. In 1.00 mol/l NaCl solution fast diffusion-limited aggregation behavior was observed with an increase in aggregate size over time described by a power law. The aggregates are characterized by a fractal dimension D=1.82. Smoluchowski and fractal theories were used to characterize the aggregation mechanism and to obtain the aggregation rate constant.
