Silicate Glasses and Melts, Second Edition describes the structure-property-composition relationships for silicate glasses and melts from a geological and industrial perspective. Updated sections include (i) characterization of silicate melt and COHN fluid structure (with and without dissolved silicate components) with pressure, temperature, and redox conditions and responses of structural variables to chemical composition, (ii) determination of solubility and solution mechanisms of COHN volatiles in silicate melts and minerals and of solubility and solution mechanisms of silicate components in COHN fluids, and (iii) effects of very high pressure on structure and properties of melts and glasses. This new book is an essential resource for researchers in a number of fields, including geology, geophysics, geoscience, volcanology, material science, glass science, petrology and mineralogy.

This book describes the structure-property-composition relationships for silicate glasses and melts of industrial and geological interest. From Antiquity to the 20th century, an introductory chapter presents this subject in a historical perspective. Basic concepts are then discussed in three chapters where attention is paid to the glass transition and its various consequences on melt and glass properties, to the structural and physical differences between amorphous and crystalline silicates, and to the mutual relationships between local order, energetics and physical properties.

With pure SiO2 as a starting point, compositions of increasing chemical complexity are successively dealt with in a dozen chapters. The effects of network-modifying cations on structure and properties are first exemplified by alkali and alkaline earth elements. The specific influence of aluminum, iron, titanium, and phosphorus are then reviewed. With water, volatiles in the system COHS, noble gases, and halogens, the effects of volatile components are also described. The last chapter explains how the results obtained on simpler melts can be applied to chemically complex systems. In each chapter, physical and chemical properties are described first and followed by a review of glass and melt structure. When possible, pressure effects are also considered.
*From SiO2 to complex silicate compositions, the physical and chemical properties of melts and glasses of geological and industrial interest
*Structural characterization of melts and glasses, from ambient to high pressure and temperature
*From basic concepts to an advanced level, a consistent description of the structure-property-composition relationships in glasses and melts

Umfassende und aktuelle Enzyklopadie rund um Herstellung, Besonderheiten, Eigenschaften, Einsatzbereiche und Geschichte von Glas Die Encyclopedia of Glass Science, Technology, History, and Culture wird den Anforderungen und Interessen einer breiten Leserschaft gerecht, die sich fur die vielfaltigen Aspekte eines des altesten, von der Menschheit genutzten Materials interessiert. UEber 100 Kapitel und 1100 Abbildungen spiegeln die praktische und uber die Zeit gewachsene Bedeutung von Glas wider, seit vor 4000 Jahren Glas zum ersten Mal hergestellt wurde. Uralte Glasgefasse, Fenster und Buntglas gehen eine Koexistenz mit neuen Hightech-Produkten ein, die beispielsweise aus Glasfasern, Dunnfilmen, metallischem, bioaktivem oder Hybridglas mit organischen und anorganischen Anteilen, amorphem Eis oder Feststoffbatterien bestehen.
