Book excerpt: Colloidal processing has always been a major processing method. It facilitates control of particle interactions through a wide variety of schemes, which include surface coating, dispersion additives, and solvent control, among others. Controlling particle interactions also permits better resultant rheology and controlled green microstructures via a wide range of forming methods. In recent years, the particle size involved has been broadened into both the nanometer and the larger than micrometer ranges. This book covers fundamental issues encountered in colloidal processing nano-(less than 0.1 micron), micro-(from 0.1 to 5 micron) and macro-(larger than 5 micron) particulate systems and at the same time explore applications for these developments.
