This volume focuses on Lifshitz—van der Waals, Lewis acid—base, and electrical double-layer interactions. Studying the first two involves measurement of the contact angles of high energy liquids deposited on solid surfaces, or use of the thin-layer wicking technique to determine the surface properties of flat or particulate solids, respectively. The interfacial free energies that occur in water among identical as well as different condensed-phase materials are derived from these surface properties, giving rise to hydrophobic attractions and hydrophilic repulsions.

Colloid Surface Properties of Clays and Related Minerals explores the distinction between polar and apolar interactions. It discusses surface properties of silica minerals, feldspars, carbonates, phosphates, sulfates, and amphibole, as well as serpentine asbestos species; analyzes the stability of aqueous suspensions of clays and other mineral particles; examines simple oxides, halides, hydroxides, and pyroxenes; covers electrophoresis and electroosmosis; clarifies protein and polymer adsorption; and more.

From the Preface: “...The surface thermodynamic data on minerals are presented in Chapter 9. Clearly, not all minerals have been examined. The study of the surface chemistry of minerals is still young, so there are a number of minerals and mineral groups which have not yet been examined. It is the hope of the authors that the present volume will stimulate others to expand our knowledge...”

Target Audience: Geologists; mining engineers; mineralogists; physical, surface, colloid, and polymer chemists and biochemists; and chemical engineers.
