Book Synopsis Introduction to Glass Science and Technology by : James E Shelby
Download or read book Introduction to Glass Science and Technology written by James E Shelby and published by Royal Society of Chemistry. This book was released on 2015-11-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Optical Properties of Rare-earth-doped Germanate Glasses by : Herbert G. Lipson
Download or read book Optical Properties of Rare-earth-doped Germanate Glasses written by Herbert G. Lipson and published by . This book was released on 1970 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Absorption spectra were used to determine the effect of modifier ions on the splitting and relative intensity of neodymium spectral terms in germanate and other glasses. The behavior of spectral components is related to the degree of inhomogeneous broadening and changes in the site symmetry of the neodymium ion. A similarity between the wavelength position of neodymium term levels and their total width in glasses and crystalline neodymium oxide has been observed. Fluorescence spectra for neodymium, erbium, and holmium ions in sodium germanate glass are reported and the absorption lines involved in excitation with both lamp and laser sources discussed. The lines of an argon-ion laser are found to be more convenient and powerful sources for the excitation of rare earth ion fluorescence than mercury vapor or tungsten lamp sources. The energy level diagram of neodymium in sodium germanate glass was determined from absorption and fluorescence peak spectra. A relationship between the strength of infrared absorption bands involved in cross-relaxation processes and the extent of neodymium fluorescence quenching was observed. Fluorescence conversion efficiencies comparable or higher than those of commercial laser glasses are found for neodymium in sodium germanate glass by both laser and lamp excitation methods. Germanate glasses show good potential as laser hosts for a number of rare earth ions. (Author).
Book Synopsis Glassy Materials Based Microdevices by : Giancarlo C. Righini
Download or read book Glassy Materials Based Microdevices written by Giancarlo C. Righini and published by MDPI. This book was released on 2019-02-28 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microtechnology has changed our world since the last century, when silicon microelectronics revolutionized sensor, control and communication areas, with applications extending from domotics to automotive, and from security to biomedicine. The present century, however, is also seeing an accelerating pace of innovation in glassy materials; as an example, glass-ceramics, which successfully combine the properties of an amorphous matrix with those of micro- or nano-crystals, offer a very high flexibility of design to chemists, physicists and engineers, who can conceive and implement advanced microdevices. In a very similar way, the synthesis of glassy polymers in a very wide range of chemical structures offers unprecedented potential of applications. The contemporary availability of microfabrication technologies, such as direct laser writing or 3D printing, which add to the most common processes (deposition, lithography and etching), facilitates the development of novel or advanced microdevices based on glassy materials. Biochemical and biomedical sensors, especially with the lab-on-a-chip target, are one of the most evident proofs of the success of this material platform. Other applications have also emerged in environment, food, and chemical industries. The present Special Issue of Micromachines aims at reviewing the current state-of-the-art and presenting perspectives of further development. Contributions related to the technologies, glassy materials, design and fabrication processes, characterization, and, eventually, applications are welcome.

The broad scope of the book includes such topics as general relationships for the response of a solid to the effect of an electromagnetic field, and specific features of optical spectrum formation for a glass and the resulting constants. The text details methods for reconstructing the spectra of optical constants from raw experimental spectra of glasses, and provides data on the spectra of optical constants in the IR and VUV ranges and on the IR band parameters for inorganic glasses. It includes factors responsible for the behavior of the refractive index dispersion of glasses in the transparency range. The reference fully details the opportunities provided by the recent version of dispersion analysis for glasses based on the specific analytical model for the complex dielectric constant. Until now, this information was only available in Russian journals. A large quantity of never-before-published data on numerical values of optical constants in the medium and far IR and of IR band frequencies and intensities is given for a wide variety of inorganic glasses. For vitreous silica, data on the optical constants are also given for the broad wavelength range in the VUV. Optical Constants of Inorganic Glasses provides the only comprehensive review of available dispersion formulas and methods for interpolating and extrapolating the refractive indices of glasses in the transparency range.

This book was released on 2017-04-09 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ceramics also known as fire clay is an inorganic, non-metallic solid article, which is produced by the art or technique of heat and subsequent cooling. The ceramics industry in India came into existence about a century ago and has matured over time to form an industrial base. From traditional pottery making, the industry has evolved to find its place in the market for sophisticated insulators, electronic and electrical items. The ceramic industry has been modernizing continuously, by newer innovations in product design, quality etc. Glass is an inorganic product typically produced by melting a mixture of silica, soda and calcium compound with desired metallic oxides that serves as coloring agents. Indian glass industry will increase on the sidelines of real estate growth across retail, residential and office estate. Glass production involves the fusion of several inorganic substances. These various substances include products such as silica sand, soda ash, dolomite and limestone, representing together 99% of all the raw materials, excluding recycled glass. Glass-ceramics are mostly produced in two steps: First, a glass is formed by a glass-manufacturing process. The glass is cooled down and is then reheated in a second step. In this heat treatment the glass partly crystallizes. In most cases nucleation agents are added to the base composition of the glass-ceramic. These nucleation agents aid and control the crystallization process. Glass-ceramics are fine-grained polycrystalline materials formed when glasses of suitable compositions are heat treated and thus undergo controlled crystallization to the lower energy, crystalline state. It is important to emphasize a number of points in this statement on glass ceramics.Glass ceramics has helped the electronics industry build much smaller and highly efficient transistors, leading to advances in all types of devices. The book covers almost all important aspects of Glass and Ceramic Industry: Properties, Applications, Manufacturing, Processing and Photographs of Plant &Machinery with Supplier’s Contact Details. The major contents of the book are types of glasses, silicate glasses, boric oxide and borate glasses, phosphorus pentoxide and phosphate glasses, germanium dioxide and germanate glasses, titanate glasses, nitrate glasses, glasses based on water, halide glasses, modern glass working, monax and pyrex glass, electric welding, photo electric cells, glassy metals, analysis of glass, glass ceramics, ceramics as electrical materials, analysis of ceramics etc. The book will be useful to the consultants, technocrats, research scholars, libraries and existing units and new entrepreneurswho will find a good base to work further in this field.

Download or read book Chemistry of Glasses written by A. Paul and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The preface ... either serves for the explanation of the purpose of the book, or for justification and as an answer to critics'. Lermontov This book is based mainly on the lectures on the Chemistry of Glasses which I gave at the University of Sheffield to the final year honours and postgraduate students of Glass Technology and Materials Science. Most books reflect the interests and enthusiasm of their authors, and the present one is no exception. The chemistry of glass is a rapidly developing field because the frontiers of advanced chemistry and advanced physics are merging together and con sequently this book will soon require considerable amplification and modification. However, my experience in teaching the chemistry of glasses for more than a decade has shown me that there is much need for a good text-book on the subject. This book is therefore intended to be a stop-gap which, until it receives that new revision. may serve as a useful reference work for students and research workers alike. I gratefully acknowledge the influence on my thinking of many of those colleagues at Sheffield with whom I have been in contact during the past twenty years or so. In addition to these personal influences, other published works have had considerable influence in modifying my approach. especially Cotton and Wilkinson's Advanced inorganic Chemistry. Dr Peter James helped me in writing Chapter 2, and Professor Peter McMillan not only read the whole manuscript but also made a number of most helpful suggestions.
