Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

In 1975, a new class of glass materials based on ZrF4 was accidentally discovered in the University of Rennes. This new family of synthetic halide glasses exhibited an exceptional wide transmission window ranging from ~ 0.2 m in the UV until ~ 7.6 m in the IR, making them a first choice for military and intelligence optical fibers, during several decades. Heavy metal fluoride glasses structure and properties are revised and discussed in this chapter.

Keywords:

Heavy metal fluoride glasses (HMFG), fluorozirconate glasses, fluorohafnate glasses, fluoride glasses, halide glasses, ZBLA, ZBN, ZBLAN.
