Abstract
Using experimentally measured nucleation and ionic strength transients, we confirm that an aggregation model can predict the particle growth profiles of Stober systems for a range of conditions. In addition, we examine the characteristics of the evolving size distribution. Systems giving the largest particles are characterized, after a short transient, by a size distribution wherein the dominant aggregation event is between the freshly generated nucleus and a large aggregate.
