Abstract : In this report are presented the results of a number of investigations of ZrF4-based and other heavy metal fluoride glasses. The purpose of these investigations has been primarily to explicate properties and behavior of these glasses relevant to their use as optical transmission media. The temperature dependence of viscosity could be described via the four parameter Cohen-Grest equation, allowing estimation of viscosities in temperature ranges where measurement of viscosity was not possible due to rapid crystallization. Characterization of the temperature dependence of Viscosity in the Region of the glass transition temperature Tg was done for a large number of HMF glasses using a differential scanning calorimetry (DSC) technique. Keywords: Brillouin Scattering; Chemical Durability, Corrosion, Dielectric Constant, Differential Thermal Analysis; Elastic Constant.
