| Abstract: | A series of fluorozirconate glasses in ZrF4-SnF2-GaF3 and ZrF4-SnF2-BaF2 systems have been studied by vibrational spectroscopy. The glass net contains not only fluorozirconate polyhedra, but also fluorostannate and fluorogallate groups. When contained in amounts of more than 10 mol.% in a glass, tin difluoride is a glass-forming agent. Gallium trifluoride in the same amount or higher forms GaF6 polyhedra. |
