Sol-Gel

Sol-Gel Materials Chemistry and Applications By John. D. Wright, University of Kent, Canterbury,UK and Nico A. J. M. Sommerdijk, Eindhoven University of Technology, The Netherlands

BOOK REVIEW

Sol-gel processing methods, first used historically for decorative and constructional materials, were extensively developed in the last century for applications such as glasses, ceramics, catalysts, coatings, composites and fibres. Today they are reaching their full potential, enabling the preparation of new generations of advanced materials not easily accessible by other methods yet using mild, low-energy conditions. The topic is therefore increasingly included in advanced undergraduate, MSc and PhD programmes in the areas of chemistry, physics and materials science. This concise introductory text, of advanced undergraduate/first-year postgraduate level, is also suitable as an introduction to the field for workers in industrial research laboratories. It offers an accessible introduction to the development, mechanisms, chemistry, characterisation methods and applications of the technique, providing the reader with an extensive yet concise grounding in the theory of each area of the subject, as well as detailing the real and potential applications and the future prospects of sol-gel chemistry.
