A preliminary investigation of chlorine XANES in silicate glasses

Evans, Katy; Mavrogenes, John; O'Neill, Hugh; Keller, Nicole; Jang, L.-Y.

Description

Chlorine speciation in silicate melts affects volatile exsolution, rheology, and thermodynamic properties of the melt but is poorly known. X-Ray Absorption Near Edge Structure (XANES) spectra have been used to investigate Cl speciation in 26 silicate glasses and to test the hypothesis that Cl in silicate melts is hosted by species that combine Cl and network-modifying cations such as Ca and Mg. Results indicate that Cl in CMAS (CaO-MgO-Al2O 3-SiO2) plus Na2O, K2O, or MnO silicate glasses exists...[Show more]
