Book excerpt: Thermal Expansion of Crystals is a comprehensive examination of the various aspects of thermal expansion of crystals. The book provides both theoretical and experimental aspects of the study of thermal expansion. Chapters are devoted to subjects on measurement methods of thermal expansion; the theory of thermal expansion; behavior of thermal expansion during the occurrence of phase transformations; and thermal expansions in ferroelectric materials. Physicists and researchers, both theoretical and experimental, in the field of thermal expansion of crystals will find this book a valuable piece of reference.
