Abstract
The importance of surface charges in establishing electrical characteristics of interfaces, particularly of the solid/liquid, liquid/gas, and liquid/liquid ones, has already been stressed in the opening paragraphs of Chapter 1. Whenever a new solid surface is formed in a gaseous or a liquid environment, as, for example, during dry or wet grinding, it either becomes charged at the moment of rupture of ionic or covalent bonds or picks up a charge by a subsequent adsorption of ions. Freshly cleaved solids remain uncharged only if the cleavage exclusively ruptures van der Waals bonds when the underlying lattice points are occupied by covalently bonded molecules and, in addition, there are in the system no mobile charges such as electrons, ions, or orientable dipoles.
