The resistance of glass to fracture is crucial for its use as a structural material in fields ranging from engineering to architecture. Here, B2O3 can play a crucial role in improving crack resistance because of the ability of B atoms to transform from 3-fold to 4-fold coordination with increasing load. However, there is little in situ information on these stress induced structural transformations, where pressures in the GPa regime are readily generated on scratching or indentation. We will use in situ high-pressure neutron diffraction to investigate the structural changes in an archetypal boro-germanate glass, a structural analogue for commercially relevant boro-silicate glass, in which structural change occurs at accessible pressures. The results will be used to build models that relate the glass structure and its deformation to the material properties.
