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 environments 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.

铝硼硅玻璃中氯局部环境的光谱学方法

我们使用光谱方法（XAS 和 XPS）研究了在 1.0 GPa 下合成的含 Na 和 Ca 的铝硼硅酸盐玻璃的氯局部环境。根据 Cl K-edge EXAFS 的结果，Cl 在玻璃中似乎显示出两种局部环境：一种位于长距离 ∼ 2.7 Å 处，属于由 Na+ 和/或 Ca2+ 补偿电荷的 Cl- 物种；另一种位于短距离 ∼ 1.8 Å 处，属于 Cl-Cl 和 Si-Cl 物种。Cl 2p XPS 结果不能明确证实存在与 Na+/Ca2+...Cl-物种重叠的 Si-Cl。
