The study of aggregation of colloidal particles involves assessment of the thermodynamics and kinetics of the process and the characteristics of the phase formed. In this article, recent contributions to the understanding of aggregation are discussed from two different perspectives: (1) developments
volume fraction F is low, aggregates settle individually and At low volume fractions, calcium carbonate colloidal suspendeposit onto the sediment; at higher volume fractions, a sions undergo cluster deposition: aggregates grow in the suspenclose packing of aggregates forms rapidly, filling the whole
Extensive numerical simulations of diffusion-limited (DLCA) and reaction-limited (RLCA) colloidal aggregation in two dimensions were performed to elucidate the concentration dependence of the cluster fractal dimension and of the different average cluster sizes. Both on-lattice and off-lattice simula
