<p>Any reaction that occurs between two substances will depend initially on the reaction, or lack of reaction, of the various atoms or molecules that are on the surface of the substances being brought into contact with each other. When reactions involving substances of very small particle size are investigated the actual detailed composition of the surface layer of these particles become of paramount importance.</p>

Hydration Layers

Abstract Hydration layer on clay mineral surfaces is originated from the adsorption of polar water molecules and hydrated cations on the surfaces through unsaturated ionic bonds, hydrogen bonds and van der Waals bonds. It has attracted great attentions because of their important influences on the dispersive stability of the particles in aqueous solutions. This review highlighted the molecular structure of clay minerals, the origin of hydration layers on clay mineral surfaces, the hydration layer structural model, hydration force and the main parameters of affecting the hydration layers on clay minerals (crystal structure, cationic type and strength, and solution pH). Also, the research methods for hydration layers were briefly described, especially the determination of hydration layer thickness by the Einstein viscosity method and AFM method. In addition, the applications of the stability of fine clay mineral particles in aqueous suspensions were summarized.
