| Characteristic coagulation time scales in colloidal suspensions are identified by using the Brownian dynamics simulation technique. Their dependence on the solid content and on the potential interaction parameters is measured. Each of these dependencies can be captured by simple formulas to reasonable accuracy. Although not all of the values for the fitted parameters meet the model expectations, a better understanding of the coagulation mechanism is gained. In particular, we deduce different cluster-cluster bonding mechanisms between the presence of an energy barrier and its absence due to the different behavior of short and long time scales under variation of the solid content and of the surface potential.
