A rheological study has been performed on fluoride glasses containing high levels of PbF 2 . Viscosity measurements in the range from 10 4.5 to 10 11 Pa s have been carried out using an oscillating parallel plate rheometer and a thermal mechanical an

In the development of research on materials for optical fibres production, the use of pure lanthanum compounds is very important for the manufacture of glasses, since they can play an important role for signal enhancement by fluorescence emission. Fo

Different processes for the preparation of fluorozirconate glasses (ZBLAN) have been investigated by infrared spectroscopy (IR) and x-ray diffraction (XRD) on fluoride powders, during the reaction. Glasses have been prepared with 20-10-5-0 (% weight)

Results are reported on crystallization modes in undoped ZBLAN and praseodymium doped ZBLAN glasses. The transformation usually proceeds from the surface with growth of oriented crystals. Activation energies of 154 and 216 kJ/mol were found for diffe
