Abstract By the use of the time-of-flight pulsed neutron total-scattering spectrometer HIT at the Japanese National Laboratory for High Energy Physics, measurement of structure factorsS(Q) for glasses of type 10Na2O·(90−x)SiO2·xTiO2 (x=0, 5 and 20 mol%) was made over a wide range of scattering vectors up toQ (=4π sinθ/λ) ~ 500 nm−1. High-resolution real-space information was obtained from the Fourier transform ofS(Q). The influence of TiO2 on the nearest-neighbour Si-O bond length of the silicate anions existing in the glass samples studied is different from that of alkali oxides such as Na2O. It is concluded that most of the Ti4+ ions predominantly substitute for Si4+ ions in their tetrahedrally coordinated sites, leading to the formation of TiO6 octahedra.
