摘要：

F-19 NMR, IR, Raman and impedance spectroscopy are used to study the ionic mobility, structure, and conductivity of 45ZrF(4)-35BiF(3)-20CsF bismuth fluorozirconate glass. With the increase in temperature from 150 K to 500 K the fluorine-containing groups pass from the rigid lattice to local movements (reorientations), and then to diffusion. According to the results of IR and Raman spectroscopy, the lattice of this glass consists of ZrF8 polyhedra linked by their vertices into chains. The glass has high ionic conductivity: sigma a parts per thousand 1.8x10(-4) S/cm in a temperature range of 480-485 K.
