Structural Evolution of MgSiO3 Glass under High Pressure and Temperature

This study investigates the structural changes in MgSiO3 glass at varying high pressure and temperature conditions, utilizing the radial distribution function (G(r)) analysis to examine the Si-Si and Mg-O-Si-O bonding. The research provides insights into the molecular arrangements and atomic interactions within the glass structure under extreme environments.
