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.
