Disperse Systems: Suspensions | SpringerLink

A flocculated suspension refers to a system in which suspended particles are formed into floccules (i.e., weakly attracted or weakly bonded aggregates of particles) rather than separate particles. In pharmaceutical formulations, controlled flocculation is a mechanism to prevent particle caking in suspension formulations.
