(abstract)

Understanding the intermediate-range ordering in oxide glasses and liquids is essential for unraveling the nature of glass transition. The combination of neutron and X-ray diffraction has been widely used for studying oxide glasses and liquids since X-rays are sensitive to heavy elements while neutrons are sensitive to oxygen. Moreover, the application of advanced simulation techniques and topological analyses, in conjunction with diffraction experiments, makes it possible to understand ‘the order within disorder’ in glasses and liquids. We report our recent findings on densified SiO2 glass, Al2O3 glass, and several high-temperature oxide liquids with a special focus on the origin of diffraction peaks.
