Abstract

The network structures of xM(2)O-(100 - x)TeO2 (M = Li, Na, Li0.62Na0.38) (X = 10, 25, 33 mol%) glasses prepared by melt quenching were studied by X-ray and neutron diffraction. The partial correlation functions for network frameworks have been calculated using the Reverse Monte Carlo (RMC) method. As a result, it was found that Te-Te correlation does not change with increasing alkali content. The RMC result supports recent reported observation that the units of TeO4 trigonal bipyramid decrease by addition of alkali oxide, while the units of TeO3 trigonal pyramid increase.
