A First contribution of the grazing incidence small angle X-ray scattering to the study of the corrosion of glass monoliths

A borosilicate glass monolith containing zirconium was corroded at 90 °C under static conditions. Grazing incidence small angle X-ray scattering (GISAXS) experiments were performed, for the first time, at the scaled intensity. The combination of chemical and GISAXS analyses allowed us to characterize the structure of the superficial layer of an altered glass monolith and to demonstrate its homogeneity in depth. Furthermore, the results obtained on monoliths, are identical to the ones obtained on grains powders, at least for this simple composition.
