CaSiO3 Glass Under Pressure: Structural Evolution, Elastic Response, and Comparison with MgSiO3 and SiO2 Glasses
We have studied CaSiO3 glass to 65 GPa using synchrotron X-ray scattering, Raman spectroscopy, and Brillouin scattering to investigate its structural and elastic evolution. X-ray scattering reveals the emergence of a new feature in the pair distribution function, g(r), near 3 Å from ∼5 GPa and a systematic shift in t...
