The field of heavy metal halide glasses (namely fluorides) is only ten years old now, but it has developed rapidly since the discovery of fluorozirconate glasses by the group at the University of Rennes (France). The main reason for this was the early demonstration of the enormous potential of such glasses for use as long-haul ultra-low loss middle infrared waveguide materials, aided in part by the scientific interest held by their unusual short range structures. As a result, significant research efforts were initiated in the academic, government and industrial sectors in Europe, the United States and Japan. However, the search for a finished product has per haps led to a partial overlooking of some of the more funda mental aspects by the scientific community. After the initial excitement, the workers in this field are perhaps at a crossroads where attenuations lower than 1 dB/Km need to be obtained for long lengths of fiber of good chemical and thermal stability, in order to guarantee continual R&D sUE ports. Therefore, there is a strong need for a critical asses sment of the potential of halide glasses for infrared fiber optics and the formulation of recommendations for future re search in this area and other related fields.

Photochromic glasses are among the most widespread types of glasses, due largely to their popular use in sunglasses. These glasses are used not only in sunglasses, but also in various opto-electronic devices that have been developed and produced throughout the world. Until now, information about photochromic glasses has been widely dispersed in the literature, much of which was published in Russian and therefore of limited accessibility to the Western world. Physics and Chemistry of Photochromic Glasses brings together the combined knowledge and understanding of photochromic glasses from these publications. Coverage includes the structure, optical properties, coloration and bleaching mechanisms, technology, and metrology of these interesting materials.

Fluoride Glass Fiber Optics reviews the fundamental aspects of fluoride glasses. This book is divided into nine chapters. Chapter 1 discusses the wide range of fluoride glasses with an emphasis on fluorozirconate-based compositions. The structure of simple fluoride systems, such as BaF2 binary glass is elaborated in Chapter 2. The third chapter covers the intrinsic transparency of fluoride glasses from the UV to the IR, with particular emphasis on the multiphonon edge and electronic edge. The next three chapters are devoted to ultra-low loss optical fibers, reviewing methods for purifying and analyzing the fluoride glass raw materials. The sources of loss are considered in Chapter 6, while the work performed on the durability of fluoride glasses is analyzed in Chapter 7. Chapter 8 focuses on the effects of radiation on fluoride glasses. The last chapter deliberates the area of active phenomena such as doping of fluoride glasses with rare-earth elements for fluorescence and lasing, as well as frequency doubling. This publication is a good reference for students and researchers conducting work on fluoride glasses.

The earliest experimental data on an oxygen-free glass have been published by Schulz-Sellack in 1870 [1]. Later on, in 1902, Wood [2], as well as Meier in 1910 [3], carried out the first researches on the optical properties of vitreous selenium. The interest in the glasses that exhibit transparency in the infrared region of the optical spectrum rose at the beginning of the twentieth century. Firstly were investigated the heavy metal oxides and the transparency limit was extended from (the case of the classical oxide glasses) up to wavelength. In order to extend this limit above the scientists tried the chemical compositions based on the elements of the sixth group of the Periodic Table, the chalcogens: sulphur, selenium and tellurium. The systematic research in the field of glasses based on chalcogens, called chalcogenide glasses, started at the middle of our century. In 1950 Frerichs [4] investigated the glass and published the paper: “New optical glasses transparent in infrared up to 12 . Several years later he started the study of the selenium glass and prepared several binary glasses with sulphur [5]. Glaze and co-workers [6] developed in 1957 the first method for the preparation of the glass at the industrial scale, while Winter-Klein [7] published reports on numerous chalcogenides prepared in the vitreous state.

Sol-Gel Techniques for Glass Producers and Users provides technological information, descriptions and characterizations of prototypes, or products already on the market, and illustrates advantages and disadvantages of the sol-gel process in comparison to other methods. The first chapter entitled "Wet Chemical Technology" gives a summary of the basic principles of the sol-gel chemistry. The most promising applications are related to coatings. Chapter 2 describes the various "Wet Chemical Coating Technologies" from glass cleaning to many deposition and post-coating treatment techniques. These include patterning of coatings through direct or indirect techniques which have became very important and for which the sol-gel processing is particularly well adapted. Chapter 3 entitled "Bulk Glass Technologies" reports on the preparation of special glasses for different applications. Chapter 4 entitled "Coatings and Materials Properties" describes the properties of the different coatings and the sol-gel materials, fibers and powders. The chapter also includes a section dedicated to the characterization techniques especially applied to sol-gel coatings and products.

Glass ••• Current Issues is the proceedings of a NATO Advanced Study Institute held in Puerto de la Cruz, Tenerife between the 2nd and 13th April 1984. The objectives of the School were twofold. Firstly to inform participants of actual and developing technolog ical applications of glassy materials in which fundamental science makes a strong contribution, and secondly to bring together scientists from the widely different backgrounds of glass science and technology to promote mutual understanding and collaboration. The amorphous state has for more than a decade now been a renaissance of scientific and technological activity extending beyond traditional glass technology research. Striking developments of amorphous materials have been made in fields such as metallurgy, electronics and telecommunications and even in disciplines until recently less concerned by materials science, such as colloid chemistry, medicine and agriculture. The physical and chemical properties brought into application here result from the interaction between the glass composition and its non-crystalline structure. One role of the basic research is to understand this interaction, which in time through development, helps to extend the range of properties and applications. In this meeting we hoped to sensitize participants to the vast range of applications of amorphous materials which exploit their unique properties, and thus broaden future investigation. The program was organised around seven topics, signposts of scientific and technological activity in the 1980'S: optical materials, amorphous metals, crystallisation phenomena, electronic and electrical devices, sol-gel preparative methods, composite materials and long-term applications.
