Soda-lime silicate glass under hydrostatic pressure and indentation: a micro-Raman study

Résumé

Raman micro-spectroscopy is used to analyse the plastic behaviour of window glass (a soda-lime silicate glass) under high hydrostatic pressure and Vickers indentation. We show pressure-induced irreversible structural changes, notably an increase of Q2 species at the expense of Q3. For the first time, a very accurate calibration curve has been established. Local density variations of a Vickers indented window glass have been characterized by micro-Raman mapping using a high spatial resolution device. The effects of glass depolymerization on indentation and hydrostatic compression are discussed. Differences between window glass and pure SiO2 glass behaviour under high stresses are also highlighted and analysed at a local scale.
