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.

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.

Non Newtonian Viscosity of Bulk Metallic Glass Forming Liquids and the Ordering and Shear Rate Induced Crystallization of Undercooled Zirconium titanium copper nickel beryllium Metallic Glass Forming Melt

Finally, the viscosities of two bulk metallic glass forming liquids Zr 57Cu15.4Ni12.6Al10Nb5 (Vit106) and Pd43Ni10Cu27P20 are measured and compared with the viscosity of Vit1. The main goal of this study was to investigate whether high viscosity and shear thinning behavior is just associated with Vit1 or the other BMG forming liquids also show such behavior. It is shown that all these glass formers show higher viscosities than monoatomic metallic liquids and surprisingly the non-Newtonian shear thinning behavior. Vit1 exhibits the highest viscosity with the largest drop in viscosity on shearing from 0.1 s-1 to 250 s-1 at the temperatures above Tliq. Vit106 shows lower viscosities than Vit1, however, a stronger non-Newtonian behavior on shearing from 0.1 s-1 to 143 s-1 at the temperatures between 1130 K and 1305 K is seen. Surprisingly, this non-Newtonian behavior disappears at higher shear rates where the viscosity stays constant. The melt viscosity of the Pd 43Ni10Cu27P20 shows a lower viscosity and much smaller shear thinning behavior than the Zr-based alloys. The viscosity data of Vit106 and Pd43Ni10Cu27P20 indicate a possibility to reach a steady state viscosity if high enough shear rates are applied to the melt of Vit1 at the temperatures between 1075 K and 1225 K. In all the three alloys, this non-Newtonian behavior gets weaker with increasing temperature and the material starts to behave like a Newtonian liquid. This behavior is attributed to the presence of MRO and short range order (SRO) in the melt of these alloys. The MRO present in the melt can be reduced by shearing and more effectively destroyed to SRO by increasing the temperature which leads to a Newtonian liquid with smaller viscosity.

This book summarizes the experimental evidence and modern classical and theoretical approaches in understanding the vitreous state, from structural problems, over equilibrium and non-equilibrium thermodynamics, to statistical physics. Glasses, and especially silicate glasses, are only the best known representatives of this particular physical state of matter. Other typical representatives include organic polymer glasses, and many other easily vitrifying organic and inorganic substances, technically important materials, amidst them vitreous water and vitrified aqueous solutions, and also many metallic alloy systems. Some of these systems only form glasses under particular conditions, e.g. through ultra-rapid cooling. This book describes the properties and the formation of both every-day technical glasses and especially of such more exotic forms of vitreous matter. It is a unique source of knowledge and new ideas for materials scientists, engineers and researchers working on condensed matter. The new edition emphasizes latest experimental findings and modern theories, explaining the kinetics of glass formation, the relaxation and stabilization of glasses and their crystallization in terms of new models, derived from the framework of the thermodynamics of irreversible processes. It shows how the properties of common technical glasses, window glass, or the vitreous ice kernel of comets can be used to develop a new understanding of the existence of matter in various, unusual forms. The described theories can even find application for the description of lasers and interesting unusual processes in the universe.

Structural Chemistry of Glasses provides detailed coverage of the subject for students and professionals involved in the physical chemistry aspects of glass research. Starting with the historical background and importance of glasses, it follows on with methods of preparation, structural and bonding theories, and criteria for glass formation including new approaches such as the constraint model. Glass transition is considered, as well as the wide range of theoretical approaches that are used to understand this phenomenon. The author provides a detailed discussion of Boson peaks, FSDP, Polymorphism, fragility, structural techniques, and theoretical modelling methods such as Monte Carlo and Molecular Dynamics simulation. The book covers ion and electron transport in glasses, mixed-alkali effect, fast ion conduction, power law and scaling behaviour, electron localization, charged defects, photo-structural effects, elastic properties, pressure-induced transitions, switching behaviour, colour, and optical properties of glasses. Special features of a variety of oxide, chalcogenide, halide, oxy-nitride and metallic gasses are discussed. With over 140 sections, this book captures most of the important and topical aspects of glass science, and will be useful for both newcomers to the subject and the experienced practitioner.
