    • Abstract


      Ion-conducting tellurite glasses are built from trigonal bipyramidal TeO4 units. Neutron diffraction as well as Raman and IR spectroscopic studies have shown that there is a continuous transition from TeO4 → TeO3+1 → TeO3 as the alkali oxide content is progressively increased, non-bridging oxygens being created in the process. Electrical conduction in both single and mixed alkali tellurite glasses is satisfactorily explained by the interchange transport mechanism, based on the site-memory effect exhibited by the glass network.
