Abstract [en]

The structure of sodium tetrasilicate (Na2Si4O9) glass and melt was studied in the range from 300 to 950 K by neutron diffraction. Increasing temperature leads to gradual decrease of the peak intensities in the static structure factors possibly with a change in the slope at the glass transition temperature (T g≅773 K), but no shift and broadening of the peaks is observed. Especially, the position of the first sharp diffraction peak (FSDP) at 1.6 Å–1 remains constant in the whole temperature range studied. The corresponding pair correlation functions g(r) are very similar at all temperatures. Only a slight broadening of the Si-O and O-O first nearest-neighbour peaks with temperature is observed, which can be attributed to temperature enhanced dynamic distortions of the SiO4 tetrahedra. All these results suggest that there is little change not only in the short- but also in the medium-range order of the sodium tetrasilicate glass and melt around the glass-liquid transition.
