Spectroscopic approach to chlorine local environment in aluminoborosilicate glasses

Year: 2024

Type: article

Abstract: Chlorine local environment has been investigated using spectroscopic approach (XAS and XPS) for Na- and Ca-bearing aluminoborosilicate glasses synthesised at 1.0 GPa. Based on Cl K-edge EXAFS results, Cl appears to show two local environment in glasses: one at long distance ~2.7 Å assigned to Cl- species charge compensated by Na+ and/or Ca2+ and one at short distance ~1.8 Å assigned to Cl-Cl and Si-Cl species. The Cl 2p XPS results cannot unambiguously confirm the presence of Si-Cl overlapped with Na+/Ca2+…Cl- species.
