COLLOIDAL SUSPENSION

Suspension in water of particles so finely divided that they will not settle under the action of gravity, but will diffuse, even in quiet water, under the random impulses of Brownian Movement. Particles typically range in size from about one micron (0.000001 millimeter) to about one millimicron; however, there is no distinct differentiation by particle size between true Suspension and colloidal suspension or between colloidal suspension and Solution.
