Abstract
The influence of zine and cadmium oxides on the structure of glasses i n the 2 TeO2.V2O5-MeO (Me=Zn, Cd) systems was investigated The glasses were prepared with a high ZnO and CdO concentration up to 75 mol %. I t was found that TeO3 units with different symmetry exist in the whole concentration range and that the increase in ZnO and CdO content caus ed changes in vanadium coordination number towards oxygen from 5 to 4. This study showed that low fold coordinated Zn2+ and Cd2+ ions with r espect to oxygen build up the network of the glasses at a high ZnO and CdO content.
