Study of Structural Transitions in Tellurite Glasses by Insitu High Pressure Neutron Diffraction

Abstract: Tellurite glasses have an interesting structural feature that Te ions have two coordinations of 3 and 4 with oxygen in the glass network. TeO2 is a conditional glass former and forms glass at very high melt-quenching rates, on adding metal oxides it forms glasses easily at low quenching rates. While the structural modifications in the tellurite network with changes in composition are well studied, the effects of thermodynamic parameters i.e. pressure and temperature on the short range structural features like Te-O speciation, bond lengths and bond angle distributions remain unexplored. This proposal aims to study insitu the effects of high pressures on the short range and medium range order in barium tellurite glasses by neutron diffraction. The studies will provide new insights on pressure induced transformations in glass structure and whether these changes are reversible or permanent.
