Cation environment and the tellurite anomaly

DOI

We have recently shown that the anomalous behaviour of the Te-O coordination number, nTeO, for binary tellurite glasses is related to the presence of terminal Te=O bonds in amorphous TeO2. A model to predict nTeO was developed and successfully applied to the K2O-TeO2 and V2O5-TeO2 systems [1]. We now wish to perform a detailed study of Li2O-TeO2 glasses to (a) test the model for an M+ cation of low coordination to oxygen and (b) examine the change in cation environment on going through the anomaly. We will use normal Li and null scattering Li in order to separate the Te-O and Li-O contributions.
