Formation and Stability of Colloidal Dispersions of Fine Particles in Water
Colloid chemistry includes an extremely broad range of substrates and dispersion media. Colloids may be solutions that consist of very large solutes or of aggregates of smaller solutes or, in contrast, may be suspensions of very fine particles, the colloidal systems of greatest interest to ceramic science are the gels and discrete particle hydrosols. This discussion will be limited to the latter. Although there are many system-specific interactions between the surface of a particulate and the solution phase, enough is known if we also limit ourselves to aqueous systems to allow us to make several generalities. We will start with a few basic considerations and definitions pertinent to this paper.
