Download or read book Glass Chemistry written by Werner Vogel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glass Chemistry is concerned with the relation of chemical composition, structure and properties of various glasses. The book has been translated from the third German edition, which serves as a textbook for university students in materials sciences and a reference book for scientists and engineers in glass science and production. The central themes of the book are the chemistry and physics of glass. Detailed knowledge of the compositional and structural facts is the basis for the systematic development of new glasses as construction and optical materials. Glass Chemistry is an interdisciplinary book on the borderlines between chemistry, physics, mineralogy and even biology and medicine. The book represents a well balanced treatment for students, scientists and engineers.

Book Synopsis Composition and Temperature Effects on Aluminoborosilicate Glasses Structure and Properties by : Jingshi Wu
Download or read book Composition and Temperature Effects on Aluminoborosilicate Glasses Structure and Properties written by Jingshi Wu and published by Stanford University. This book was released on 2011 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Elasticity and Strength in Glasses by : D Uhlmann
Download or read book Elasticity and Strength in Glasses written by D Uhlmann and published by Elsevier. This book was released on 2012-12-02 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glass: Science and Technology, Volume 5: Elasticity and Strength in Glasses covers the scientific and engineering aspects of glass elasticity and strength. This volume is organized into six chapters and begins with the examination of the elastic properties of vitreous silica and silicate glasses, including those that contain moderate amounts of other network formers. The following chapters describe the fracture mechanics and inelastic deformation of oxide, metallic, and polymeric glasses. The discussion then shifts to the concept of glass strengthening approaches and some technologies of significant practical application to glasses. A chapter explores the process of thermal tempering of glass, including the physics, theories, and standards of the process. The last chapter focuses on the practical aspects of chemical strengthening and the mechanical and physical properties of the obtained glass. This book is of great benefit to glass scientists and researchers.

Book Synopsis On the Fracture Behaviour and the Fracture Pattern Morphology of Tempered Soda-Lime Glass by : Navid Pour-Moghaddam

This book was released on 2019-11-08 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main criteria for assessing the load-bearing behaviour and risk potential of monolithic glass are its fragmentation and the morphology of the fragments. These depend strongly non-linearly on the strain energy density present in the glass at the time of fracture, which can be converted into fracture energy. Thus, the design and optimization of structural glazing in engineering requires both knowledge of the relevant parameters and mechanisms during the fracture process in glass and an understanding of the characteristics of the fracture structure. Based on fracture mechanics considerations and comprehensive experimental investigations, various aspects and physical quantities of fracture behaviour as well as characteristics and parameters of fracture pattern morphology of fragmented, tempered soda-lime glass were studied and correlated with the stored strain energy. The relationship between fragmentation behavior and strain energy was elaborated using the energy criterion in Linear Elastic Fracture Mechanics (LEFM) related to the initial strain energy before fragmentation and in the post-fracture state. Furthermore, a machine learning inspired approach for the prediction of 2D macro-scale fragmentation of tempered glass was developed and elaborated based on fracture mechanics considerations and statistical analysis of the fracture pattern morphology. A method was deduced and applied in which the fracture pattern of tempered glass is predicted and simulated by Voronoi tessellation of point patterns based on Bayesian spatial point statistics fed with energy conditions in LEFM.

Book Synopsis Mathematical Approach to Glass by : Miloš Bohuslav Volf
Download or read book Mathematical Approach to Glass written by Miloš Bohuslav Volf and published by Elsevier Science Limited. This book was released on 1988 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although completely self-contained, this book forms a useful supplement to Volf's Chemical Approach to Glass (1984) in which the account of the manifestation of the individual elements in oxide glasses was described phenomenologically. Aimed at facilitating active study of glass by means of calculations, this book is directed towards a quantification of the manifestation of elements in glass and interpolation of the chemical and physical dependence of the properties of glass. Thanks to the availability of computer technology and to increasing cooperation between glass scientists and mathematicians, the field of applied mathematics in glass has expanded and is developing into a separate discipline with its own systems and methods, internal classification, and links to other disciplines. The concept of calculations in glassmaking has therefore outgrown its original scope. It has ceased to be a mere collection of formulas and tables and is moving away from the apparently accidental peculiarities related to the nonstoichiometry of glass to an order dictated by the periodical system of elements.
