Heavy metal Γuoride glass ZBLAN, with molar composition ZrF 4 (53)-BaF 2 (20)-LaF 3 (4)-AlF 3 (3)-NaF(20), was studied in vacuum at high temperatures up to 480 ΓC by Raman spectroscopy. The vitreous glass was found to crystallize at 330 ΓC, most probably to crystallites. High-temperature experiments

Several compositions in the (50x ) PbO-xPbF 2 -50B 2 O 3 (0 Γ x Γ 20) mol% vitreous system were systematically characterized at room temperature by infrared and Raman microscopic analysis. A general assignment of the vibrations observed for x = 0 mol% was proposed on the basis of borate units and co
## Abstract The presence of magnesium in glasses of geological, medical, and technological interests influences their physicochemical and durability properties. However, the understanding of the role of magnesium is dependent on the combined knowledge of the structural environment of magnesium in t
