Synthesis and Ion Mobility in Glasses of ZrF4–BiF3–Rb(Cs)F Fluoride Systems
A new procedure has been suggested for the synthesis of bismuth fluorozirconate glasses in the ZrF 4 –BiF 3 –MF systems (M = Rb, Cs), which is based on the use of the relatively moisture-resistant Rb 2 ZrF 6 and Cs 2 ZrF 6 fluorides rather than extremely hygroscopic rubidium and cesium fluorides.
