Colloids A Working Definition

TABLE 10.1. Dlustrative Examples of Practical Applications of Colloids and Colloidal Phenomena 

Pharmaceuticals, cosmetics, inks, paints, foods, lubrication, food products, dyestuffs, foams, agriculture chemicals Photographic products, ceramics, paper coatings, magnetic media, catalysts, chromatographic adsorbents, membrane and latex film, electrophotographic toners 

Handling properties of colloids, rheology, sintering Destruction of unwanted colloidal phenomena 

To define a colloid more or less adequately one must consider two aspects of the system structure—how the components of the system are put together or mixed—and size—what the dimensions are of the dispersed units in the system.
