Colloid aggregation processes, interparticle

We have already introduced the idea that the primary particles of a dispersed system tend to associate into larger structures known as aggregates. The nature of the interparticle forces responsible for this aggregation is one of the most examined areas of colloid science. We defer our discussion of the aggregation (or coagulation) process until Chapter 13, but a few remarks about aggregates — the kinetic units that result from that process —and how their dimensions are represented quantitatively are in order at this time.
