Multi-method characterization of soda-lime glass corrosion - Part 1. Analysis techniques and corrosion in liquid water - Report of the International Commission on Glass (ICG) Subcommittee of Technical Committee 19 "Glass Surface Diagnostics"

Corroded soda-lime float glass surfaces prepared in water (room temperature and 60 degreesC) or air (relative humidity of 95 %, 60 degreesC) for diffe rent times are investigated by means of SIMS, SNMS, XPS, NRA, ERD, RES, GIX R, AFM, SEM, light microscopy and scratch testing. The corrosion effects ar e studied for as-received and cleaned glass surfaces. Changes in the elemen t concentration in the glass interfaces with the immersion time in water ar e described. They are combined with variations in density of the surface la yer which exhibits plastic deformation behaviour. Inhomogeneous corrosion l eads to changes in the topography and an increase in surface roughness.
