The data sets describe the effect on the structure of glassy (MgO)_{0.375}(Al_2O_3)_{0.125}(SiO_2)_{0.5} of increasing the pressure from ambient to 8.2 GPa. They also describe the effect on the structure of releasing the pressure from 8.2 GPa and recovering the glass to ambient conditions. The structure was measured using in situ high pressure neutron diffraction. The coordination environment of aluminium in the as-prepared and recovered material was also probed using solid state 27Al nuclear magnetic resonance spectroscopy. 2024-01-25 University of Bath public RightsHolder University of Bath Royal Society https://doi.org/10.13039/501100000288 DH140152 Dorothy Hodgkin Research Fellowship - Rational Design of Glassy Materials with Technological Applications Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 DH140152 Dorothy Hodgkin Research Fellowship - Rational Design of Glassy Materials with Technological Applications Corning https://doi.org/10.13039/100008280 CM00002159/SA/01 Structural role of magnesium in glass and glass-ceramics cent_nan cent_netcb The data sets were collected using the methods described in the published paper.
