The author describes a novel method of preparing hydrolysis-stable non-silicate glasses which is based on experimental work accomplished over the past twenty years. As such, the method is the beginning of a new approach to glass-making by the use of a molecularly-polymerizable precursor. The book elucidates the technical details required to produce such molecularly-polymerized glasses from carefully prepared inorganic molecular monomers. Essentially, only silicate-based glasses have been known to be stable, whereas non-silicate glasses could not be attributed with such properties. Such glasses have, therefore, not found widespread usage in industry. The new phosphate glasses described here exhibit stabilities superior to many of the silicate glasses. For example, the nuclear-waste glass shows no measurable loss at all in boiling water, something entirely foreign to the zinc borosilicate glasses developed for nuclear waste encapsulation in the U.S. by Battelle-Northwest. The exceptional stability of the new glasses is achieved by selecting an inorganic compound capable of being polymerized, and then causing it to polymerize in a proper manner, in the absence of chain-stoppers. To obtain glasses equal or superior in hydrolysis stability to silicate-based systems it is imperative to employ molecular polymerization in situ, starting from carefully prepared precursors of exact stoichiometric proportion. Researchers in glass and glass properties will find this volume extremely useful and those involved in organic polymers will be intrigued by the similarities and disparities of the two systems.

This new book is devoted to the problem of the frequency dispersion of optical constants of inorganic glasses. It is the only source providing a comprehensive discussion of this topic on a unified physical and analytical basis. Optical Constants of Inorganic Glasses presents thorough descriptions of the underlying physical phenomena, analytical models for the optical constants dispersion, and detailed information on the optical constants and related optical characteristics of glasses. 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. The volume is a valuable resource for researchers, practitioners in the fields of glass technology and applied optics, and students.
