摘要
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。
Spectroscopic approach to chlorine local environment in aluminoborosilicate glasses
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.
