Glass continues to be a material of great scientific and technological interest; however, the economic pressures on the glass industry, the emphasis on global markets, and the worldwide attention to energy and environmental conservation continue to increase. Forty-seven papers offer new solutions to the challenges of glass manufacturing, particularly as they pertain to melting and forming.

This book provides a concise and inexpensive introduction for an undergraduate course in glass science and technology. The level of the book has deliberately been maintained at the introductory level to avoid confusion of the student by inclusion of more advanced material, and is unique in that its text is limited to the amount suitable for a one term course for students in materials science, ceramics or inorganic chemistry. The contents cover the fundamental topics of importance in glass science and technology, including glass formation, crystallization, phase separation and structure of glasses. Additional chapters discuss the most important properties of glasses, including discussion of physical, optical, electrical, chemical and mechanical properties. A final chapter provides an introduction to a number of methods used to form technical glasses, including glass sheet, bottles, insulation fibre, optical fibres and other common commercial products. In addition, the book contains discussion of the effects of phase separation and crystallization on the properties of glasses, which is neglected in other texts. Although intended primarily as a textbook, Introduction to Glass Science and Technology will also be invaluable to the engineer or scientist who desires more knowledge regarding the formation, properties and production of glass.

This book is the result of a study to develop a high-temperature melt properties database with sufficient comprehensiveness and reliability to allow mathematical modeling of glass melting and forming processes for improved product quality, improved efficiency and lessened environmental impact. The study was initiated by the U.S. glass industry through the National Science Foundation Industry/University Center for Glass Research at Alfred University (CGR) and funded in part by a grant from the U.S. Department of Energy's Industrial Technologies Program.

A comprehensive and up-to-date encyclopedia to the fabrication, nature, properties, uses, and history of glass The Encyclopedia of Glass Science, Technology, History, and Culture has been designed to satisfy the needs and curiosity of a broad audience interested in the most varied aspects of material that is as old as the universe. As described in over 100 chapters and illustrated with 1100 figures, the practical importance of glass has increased over the ages since it was first man-made four millennia ago. The old-age glass vessels and window and stained glass now coexist with new high-tech products that include for example optical fibers, thin films, metallic, bioactive and hybrid organic-inorganic glasses, amorphous ices or all-solid-state batteries. In the form of scholarly introductions, the Encyclopedia chapters have been written by 151 noted experts working in 23 countries. They present at a consistent level and in a self-consistent manner these industrial, technological, scientific, historical and cultural aspects. Addressing the most recent fundamental advances in glass science and technology, as well as rapidly developing topics such as extra-terrestrial or biogenic glasses, this important guide: Begins with industrial glassmaking Turns to glass structure and to physical, transport and chemical properties Deals with interactions with light, inorganic glass families and organically related glasses Considers a variety of environmental and energy issues And concludes with a long section on the history of glass as a material from Prehistory to modern glass science The Encyclopedia of Glass Science, Technology, History, and Culture has been written not only for glass scientists and engineers in academia and industry, but also for material scientists as well as for art and industry historians. It represents a must-have, comprehensive guide to the myriad aspects this truly outstanding state of matter.

This is the fourth volume of a comprehensive reference work on the properties of one-component, binary and ternary oxide glass-forming melts and glasses. Part A Silica Glass and Binary Silicate Glasses'' was published in 1983, and Part B Single-Component and Binary Non-Silicate Oxide Glasses'' in 1985. Part C, published in 1987, covered Ternary Silicate Glasses. The present volume covers ternary non-silicate glasses. All ternary systems are united into large groups according to the valency of the elements forming the corresponding oxides. Within each of these groups the data are classified by properties. The sequence is as follows: glass formation, crystallization, density, thermal expansion and other thermal properties, optical properties, viscosity, elastic properties and internal friction, strength, surface tension, chemical durability, electrical properties, diffusion, permeation and solubility of gases, ion diffusion, volatilization and magnetic properties. Extensive references are included, as are author, subject and formula indexes.This book is an essential aid for all those working in research laboratories of glass-making firms, university lecturers, and undergraduate/post-graduate students involved with materials science. Previous parts have already proved their usefulness to a great many people and have been described as follows: The Handbook of Glass Data cannot be recommended too strongly. It must be held in every library where there is a serious interest in glass, and it should be on the shelf of every glass researcher. (Glass Technology).

This works studies the effects of compositional and temperature variations on the structure and properties of aluminoborosilicate glasses. Two groups of aluminoborosilicate glasses, one that has lower boron content and another that has higher boron content, have been studied. The structural changes were mainly observed with high-field B-11, Al-27 and Na-23 magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy. In these glasses, boron is either three-coordinate (BO3) or four-coordinate (BO4); aluminum exists predominately as four-coordinate species, but there is a small amount of five-coordinate aluminum ([5]Al). The compositional study focused on the effect of the cation field strength of the network modifiers on the glass structure by varying the ratio of the two network modifiers, CaO and Na2O. Increasing the ratio of CaO to Na2O dramatically lowers the fraction of four-coordinated boron (N4), increases [5]Al, and increases the fraction of non-bridging oxygens (NBO), which was calculated based on the boron and aluminum structural information. However, variations in these fractions are not linear with respect to the average cation field strength. Na-23 spectra reveal that the ratio of bridging to non-bridging oxygens in the coordination shell of Na+ increases with an increasing ratio of CaO to Na2O in Ca-rich glasses. These changes can be understood by the tendency of higher field strength modifier cations to facilitate the concentration of negative charges on NBO in their local coordination environment, systematically converting BO4 to BO3. The effect of temperature on the structure was studied by two ways: cooling the glass-forming melts at different rates to sample the glass structure at different fictive temperature, and using high-temperature in situ NMR. The abundances of BO3 and NBO increase with increasing fictive temperature, suggesting that the reaction BO4 [logical equivalence] BO3 + NBO shifts to the right with increasing temperature. The observed temperature dependence of the abundance of BO4 species allows us to estimate the enthalpy of reaction, [Delta]H, which is closely related to the amount of NBO in the glass. In situ high-T B-11 MAS NMR was used to observe chemical exchange between BO3 and BO4 species over the timescale of microseconds to seconds. The timescale of BO3/BO4 exchange from NMR data, [lowercase Tau](NMR), appears to be "decoupled" from that of the macroscopic shear relaxation process, [lowercase Tau](s), derived from the viscosity data; however, at higher temperatures, [lowercase Tau](s) approaches [lowercase Tau](NMR). The "decoupling" at lower temperature may be related to intermediate-range compositional heterogeneities, and /or fast modifier cation diffusivities, which trigger "unsuccessful" network exchange events.
