New book applies superior model to improve understanding of vitreous materials

Phonon Dispersion Treatment of the Thermodynamic and Physical Properties of vitreous and Disordered Solids"Phonon Dispersion Treatment of the Thermodynamic and Physical Properties of Vitreous and Disordered Solids" by Edgar F. Westrum Jr. and David A. Johnson addresses the unique properties of amorphous solids

"Phonon Dispersion Treatment of the Thermodynamic and Physical Properties of Vitreous and Disordered Solids" (ISBN 1463520239), a scientific treatise by Edgar F. Westrum Jr. and David A. Johnson, seeks to replace Debye's inferior model of vitreous solids with the Phonon Dispersion Model developed by Stephen Barber and Dr. Westrum.

Edgar F.Westrum, JrProduced at an annual rate of 100 million tons, silicate glass is one of the most ubiquitous materials in the contemporary world. Attempts to understand its properties, as well as those of other vitreous solids, have lagged behind those of similar ordered solids because the properties are so unique. Dr. Westrum and Dr. Johnson argue that Debye's model, in use for decades, should be rejected because of its inappropriate assumption of a constant phase velocity despite evidence to the contrary. This volume describes the Phonon Dispersion Model and argues for its superiority through detailed application to a wide range of amorphous solids.

"Since the Model provides structural, physical, and thermal properties of amorphous materials, its use will lead to the development of better glass for commercial applications and will impact our understanding of the relatively new glassy metals or metallic glasses as well as geological glassy materials," says Dr. Westrum.

Written by two of the leading researchers in the field, including one of the developers of the model, the book is intended to provide the best available resource on this unique group of materials.

"Phonon Dispersion Treatment of the Thermodynamic and Physical Properties of Vitreous and Disordered Solids" is available for sale online at and other channels.

About the Author

Edgar F. Westrum Jr. received his doctorate in physical chemistry from the University of California

Berkeley. One of the world's scientific leaders in the area of thermodynamics and physical properties of solids since 1940, he has published more than 600 research books and papers since that time. He has served as a member of the chemistry faculty at the University of Michigan since 1946, co-founded the Journal of Chemical Thermodynamics and the Calorimetry Conference and participated as reviewer and consultant to major committees of the National Institute of Technology and the Committee on Data for Science and Technology (CODATA).

David A. Johnson received his doctorate in chemistry from Louisiana State University and has served as a professor at Spring Arbor University since 1966. Since 1990, Dr. Johnson has collaborated with Dr. Edgar Westrum in studying the thermal behavior of solids using equilibrium adiabatic calorimetric techniques, research that has resulted in eight publications in major journals.
