Characterization of the relationships between structure and properties of materials is based on the fundamental principle that the structure of the material be determined first, followed by assessments of which structural properties may govern their properties as a function of composition, pressure, temperature and other variables. Whereas this methodology has been successfully applied to further our understanding of crystalline materials, studies of silicate melt structure are often conducted on a somewhat different basis. Rather than from direct structural determination, structure models have been developed from assumed relationships between a specific melt property and its structure. As a result, a multitude of models has evolved - many of which are mutually exclusive. The overall scope of this book is to address properties and processes of magmatic systems from the vantage point of melt structure. To this end available data in chemically increasingly complex systems are reviewed and discussed with the ultimate goal being integration of the simple system data into a model that describes complex systems such as natural magmatic liquids. Thus the book evolves from the simplest possible system, SiO 2 , to complex systems such as natural magmatic liquids. From a petrologic point of view, sufficient data have been obtained so that a general framework of the structure of magmatic liquids is in place. This framework is based on the same principles as those of crystal chemistry, modulated by the absence of long range order in amorphous material, and systematic relationships between structure and properties can be discerned at least at atmospheric pressure.

Physical Sciences Data, Volume 15: Handbook of Glass Data: Silica Glass and Binary Silicate Glasses, Part A presents information on the systems capable of forming glasses by cooling melts. This book provides data on the crystallization rates of glasses. Organized into six chapters, this volume begins with an overview of the melt properties for the glass-forming systems. This text then examines the notion of a component that is very significant for determining the number of components in each investigated glass. Other chapters consider the contents of several oxides of the same element but in different valent state as the reason to transfer a glass to the category of the increased number of components. This book discusses as well the analytical composition of glass. The final chapter deals with flotation method using tetrabromoethane and benzene mixture. This book is a valuable resource for glass specialists, chemists, engineers, scientists, and information science workers.

Volume 32 of Reviews in Mineralogy introduces the basic concepts of melt physics and relaxation theory as applied to silicate melts, then to describe the current state of experimental and computer simulation techniques for exploring the detailed atomic structure and dynamic processes which occur at high temperature, and finally to consider the relationships between melt structure, thermodynamic properties and rheology within these liquids. These fundamental relations serve to bridge the extrapolation from often highly simplified melt compositions studied in the laboratory to the multicomponent systems found in nature. This volume focuses on the properties of simple model silicate systems, which are usually volatile-free. The behavior of natural magmas has been summarized in a previous Short Course volume (Nicholls and Russell, editors, 1990: Reviews in Mineralogy, Vol. 24), and the effect of volatiles on magmatic properties in yet another (Carroll and Holloway, editors, 1994: Vol. 30). The Mineralogical Society of America sponsored a short course for which this was the text at Stanford University December 9 and 10, 1995, preceding the Fall Meeting of the American Geophysical Union and MSA in San Fransisco, with about 100 professionals and graduate students in attendance.

Carbonate-rich silicate and carbonate melts play a crucial role in deep Earth magmatic processes and their melt structure is a key parameter, as it controls physical and chemical properties. Carbonate-rich melts can be strongly enriched in geochemically important trace elements. The structural incorporation mechanisms of these elements are difficult to study because such melts generally cannot be quenched to glasses, which are usually employed for structural investigations. This thesis investigates the influence of CO2 on the local environments of trace elements contained in silicate glasses with variable CO2 concentrations as well as in silicate and carbonate melts. The compositions studied include sodium-rich peralkaline silicate melts and glasses and carbonate melts similar to those occurring naturally at Oldoinyo Lengai volcano, Tanzania. The local environments of the three elements yttrium (Y), lanthanum (La) and strontium (Sr) were investigated in synthesized glasses and melts using X-ray absorption fine structure (XAFS) spectroscopy. Especially extended X-ray absorption fine structure spectroscopy (EXAFS) provides element specific information on local structure, such as bond lengths, coordination numbers and the degree of disorder. To cope with the enhanced structural disorder present in glasses and melts, EXAFS analysis was based on fitting approaches using an asymmetric distribution function as well as a correlation model according to bond valence theory. Firstly, silicate glasses quenched from high pressure/temperature melts with up to 7.6 wt % CO2 were investigated. In strongly and extremely peralkaline glasses the local structure of Y is unaffected by the CO2 content (with oxygen bond lengths of ~ 2.29 Å). ...

This book presents state-of-the-art information concerning properties and processes involved in glass melts. Based upon contributions by renowned authors and scientists working with glass melt systems, Properties of Glass-Forming Melts is an excellent compilation of the current knowledge on property data, mechanisms, measurement techniques, and structure-related properties of glass-forming. The authors provide in-depth analyses of such topics as glass-melt density, thermal expansion, heat conductivity, and chemical activities. Each chapter combines fundamental concepts with a compilation of recent and reliable data that is essential in the modeling of glass melting, fining, conditioning, and forming. The book first discusses the glass-forming melts, thermodynamics, transport properties, and redox effects of glass. This provides a sound basis to the analysis of important properties of glass melts such as viscosity, surface tension, density, and heat capacity as well as more generalized subjects of heat transfer and gas solubility. A chapter on electrical properties provides a solid foundation for understanding glass melting via direct Joule heating of the melt. The examination of the corrosive nature of molten glasses will be of great interest to tank designers and operators. This unique handbook concludes with an overview of nuclear waste vitrification, a growing discipline that relies on current data and encourages research in glass melts. This book is an ideal starting place for future-generation glass scientists and an effective reference for scientists who require data on the behavior of viscous melts and for glass technologists who apply mathematical models simulating the melting and forming processes. Properties of Glass-Forming Melts offers a one-of-a-kind and valuable source of reliable data and insight by those with firsthand knowledge and experiences in this field.
