Abstract
The nature of the Te-O bond and charge transfer between alkali atoms and Te-O polyhedra in alkali-tellurite glasses is discussed in connection with ion transport in these glasses. Experimental results on XPS, neutron and Raman scattering support the empirical picture developed here. The overall kinetics of the interchange transport mechanism for conduction in single and mixed alkali-tellurite glasses is apparently determined by the kinetics of the alkali ion—glass former ion interchange—an aspect to be probed experimentally.
