Saxs Study Of The Micro-Inhomogeneity Of Industrial Soda-Lime-Silica Glass

The microstructure of a variety of industrial multicomponent soda-lime glasses for containers and glazing and of a lead silicate glass for pressed tableware articles was analysed using small angle X-ray scattering (SAXA). No inhomogeneity with size .0,5nm was found in the industrial samples, while ternary soda-lime glass samples with suitable composition developed under heat treatment a phase separation easily detected by SAXS. The results obtained disprove earlier reports which attributed problems of rheology and strength affecting container production ("poor workability") to microstructure formations.
