Surface analysis data from in-situ testing of ferri-silicate Truw glass WG 124 in WIPP-MIIT facility

Description

TRUW ferri-silicate glass samples corroded for six and twelve months in the MIIT (Materials Interface Interaction Test) facility in the WIPP-site in New Mexico, were investigated by SEM-EDXA and EMP X-ray analysis. The corroded glass surfaces present a double structure, consisting of an outer surface (alteration) layer, containing mainly Mg and Cl, several μm thick, and a subsurface (reaction) zone 4 μm (6 months) to 7 μm (12 months) thick, depleted in the glass constituent Na. This subsurface zone is believed to be indicative for the glass dissolution. Additional surface analyses are required to further validate these preliminary conclusions
