In the decade since glass-ceramics first became mass-pro duced articles of commerce, they have become a popular subject for research and invention, as attested to by the 773 references cited in this book. Discovered almost accidentally during re search on photosensitive glasses, thermally crystallized glass ceramics have been distinguished by the rapid pace of their utili zation for distinctive new products. This promise has been recognized throughout the world, and original contributions have appeared from nearly every country having an ongoing glassmaking capability. Particularly numerous have been the publications and the ideas, scientific and technolOgi cal, issuing from the USSR. For several years, the annual All Union Conference on the Glassy State has been dominated by papers on catalyzed crystallization of glasses. With regard to new prod uct lines, we learn about slag-based sitaUs (glass-ceramics) and also about specialty items derived by radiation-assisted crystalli zation in glasses, photo-sitaUs. A. I. Berezhnoi has written a comprehensive review of the publications on this topic, which includes a balanced weighting to the contributions from the USSR and the USA, and also introduces advances from Britain, Czechoslovakia, Romania, Japan, and other centers of activity.

This book, entitled Low Thermal Expansion Glass Ceramies, is one of aseries reporting on research and development acitivites on products and processes conducted by the Schott Group. The scientifically founded development of new products and technical pro cesses has traditionally been of vital importance at Schott and has always been performed on a sc ale determined by the prospects for application of our special glasses. The scale has increased enormously since the reconstruction of the Schott Glaswerke in Mainz. The range of expert knowledge required for that could never have been supplied by Schott alone. It is also a tradition in our company to cultivate collaboration with customers, universities, and research institutes. Publications in numerous technical journals, which since 1969 we have edited to a regular timeplan as Forschungsberichte - 'research reports' - formed the basis of this cooperation. They contain up-to-date infor mation on various topics for the expert but are not suited as survey material for those whose standpoint is more remote. This is the point where we would like to place our series, to stimulate the exchange of thoughts, so that we can consider from different points of view the possibilities offered by those incredibly versatile materials, glass and glass ceramics. We would like to show scientists and engineers, interested customers, and friends and employees of our firm the knowledge that has been won through our research and development at Schott in cooperation with the users of our materials.

This completely revised edition features new sections on glass-ceramic applications and their performance, CDC-grinding, and laser gyroscopes containing Zerodur®., providing an overview of Schott's activities for scientists, engineers, and managers.

The safe storage in glass-based materials of both radioactiveand non-radioactive hazardous wastes is covered in a single book,making it unique Provides a comprehensive and timely reference source at thiscritical time in waste management, including an extensive andup-to-date bibliography in all areas outlined to waste conversionand related technologies, both radioactive and non-radioactive Brings together all aspects of waste vitrification, drawscomparisons between the different types of wastes and treatments,and outlines where lessons learnt in the radioactive waste fieldcan be of benefit in the treatment of non-radioactive wastes

A comprehensive and up-to-date encyclopedia to the fabrication, nature, properties, uses, and history of glass The Encyclopedia of Glass Science, Technology, History, and Culture has been designed to satisfy the needs and curiosity of a broad audience interested in the most varied aspects of material that is as old as the universe. As described in over 100 chapters and illustrated with 1100 figures, the practical importance of glass has increased over the ages since it was first man-made four millennia ago. The old-age glass vessels and window and stained glass now coexist with new high-tech products that include for example optical fibers, thin films, metallic, bioactive and hybrid organic-inorganic glasses, amorphous ices or all-solid-state batteries. In the form of scholarly introductions, the Encyclopedia chapters have been written by 151 noted experts working in 23 countries. They present at a consistent level and in a self-consistent manner these industrial, technological, scientific, historical and cultural aspects. Addressing the most recent fundamental advances in glass science and technology, as well as rapidly developing topics such as extra-terrestrial or biogenic glasses, this important guide: Begins with industrial glassmaking Turns to glass structure and to physical, transport and chemical properties Deals with interactions with light, inorganic glass families and organically related glasses Considers a variety of environmental and energy issues And concludes with a long section on the history of glass as a material from Prehistory to modern glass science The Encyclopedia of Glass Science, Technology, History, and Culture has been written not only for glass scientists and engineers in academia and industry, but also for material scientists as well as for art and industry historians. It represents a must-have, comprehensive guide to the myriad aspects this truly outstanding state of matter.
