Nucleation And Crystallization In Glasses

The E-book "Nucleation and Crystallization of Glasses and Glass-Ceramics" highlights historic perspectives and current research in the field of glass-ceramic technology. Glass-ceramic technology is promising to provide us with materials of high strength, high toughness, unique electrical/electronic or magnetic properties, exceptional optical or unusual thermal or chemical properties. The greater diversity of microstructure-property arrangements and processing routes over glasses and ceramics are responsible that glass-ceramics are the preferred choice of materials in many technical, consumer, optical, medical/dental, electrical/electronic, and architectural fields. This includes increasing uses of glass-ceramic materials for environment and energy applications in the last decades. The positive development of glass-ceramic technology has become true in particular due to the pioneering spirit, resourcefulness, and courage of researchers of the first generation. Extraordinary and, therefore, to be distinguished is the work of the glass-ceramic inventor S. Donald Stookey to whom this Research Topic is dedicated. The authors, all experts in the field of glass-ceramics and based in industry, academia and governmental institutions, contributed to this E-book under the guidance of the Technical Committee 07 "Crystallization and Glass-Ceramics" of the International Commission on Glass (ICG).

Structure and Crystallization of Glasses details glass structural analysis from an experimental perspective. The book is comprised of eight chapters that cover various structural concepts. The text first introduces the basic elements of glass structures, and then proceeds to discussing the development of classical structure theories. The next chapter presents research that deals with structure of prototype and original glasses. Next, the book details the position of the structural conceptions resulting from the studies. Chapter 5 talks about the crystallization behavior of glasses according to the classical studies of G. Tammann and their development. Chapter 6 deals with the effects of the composition of glass on the resulting form of a crystal phase in the course of growth. The seventh chapter discusses the microphases in glass and their relations to crystallization, and the last chapter details the directed crystallization in glass. The text will be of great use to individuals involved in the research, development, and application of glass technology, such as materials engineers and inorganic chemists.

“This book contains overviews on technologically important classes of glasses, their treatment to achieve desired properties, theoretical approaches for the description of structure-property relationships, and new concepts in the theoretical treatment of crystallization in glass-forming systems. It contains overviews about the state of the art and about specific features for the analysis and application of important classes of glass-forming systems, and describes new developments in theoretical interpretation by well-known glass scientists. Thus, the book offers comprehensive and abundant information that is difficult to come by or has not yet been made public.” Edgar Dutra Zanotto (Center for Research, Technology and Education in Vitreous Materials, Brazil) Glass, written by a team of renowned researchers and experienced book authors in the field, presents general features of glasses and glass transitions. Different classes of glassforming systems, such as silicate glasses, metallic glasses, and polymers, are exemplified. In addition, the wide field of phase formation processes and their effect on glasses and their properties is studied both from a theoretical and experimental point of view.

This book provides an up-to-date and comprehensive coverage of the properties of glasses as materials and of the vitreous state in general. The broad coverage of the book includes a study of the methods of studying the structure, glass classification, and electrical, optical, thermal and mechanical properties of glasses.
