the book will deal with the dispersion of powders in liquids to prepare suspensions that are applied in many industries: paints, cosmetics, agrochemicals, pharmaceuticals, liquid detergents, etc. this will be a unique book covering both the fundamentals of powder dispersions in liquids as well as control of the stability of the resulting suspensions. applications of these fundamental principles to various formulations will be covered. the book will consist of 15 chapters covering the principles of powder wetting and dispersion, the role of surfactants in powder dispersion, the structure of the solid/liquid interface and electrostatic stabilization, the concept of zeta potential and its application, general classification of dispersing agents, adsorption of surfactants and polymers at the solid/liquid interface, stabilization of suspensions using polymeric surfactants and the theory of steric stabilizations, properties of concentrated dispersions, characterization of suspensions using particle size measurements, rheology of concentrated suspensions, use of rheological methods for assessment and prediction of the long term physical stability of suspensions.
