Abstract
The ionic mobility and electrical transport in 45ZrF4 · 35BiF3 · 20MF (M - Li, Na, K) glasses have been studied by 7Li, 19F, and 23Na NMR and impedance spectroscopy at temperatures from 200 to 500 K. In the range 400–440 K, the main kinds of ionic mobility in these glasses are local motions of fluorine-containing groups and lithium ion diffusion. The temperature range where the dominant kind of ion motion in the glasses is fluoride ion diffusion depends on the nature of the M+ cation. Above 470 K, the glasses offer rather high ionic conductivity: σ ≥ 10−5 S/cm.
