Abstract

The leaching and dissolution behavior of two sodium-aluminosilicate glasses, with structures containing one versus five non-bridging oxygen sites per 10 tetrahedra, is discussed for both acid (pH 2) and base (pH 9) reactions. The soda concentration was held constant at 25 mol%. X-ray photoelectron spectroscopy, secondary ion mass spectroscopy and Fourier transform infrared reflection spectroscopy have been used to determine the composition and structure of the reacted glass surfaces. The glass with five NBO sites per 10 tetrahedra exhibits extensive surface layer formation in both acid and base. Conversely, the glass with one NBO site per 10 tetrahedra exhibits total dissolution in acid; in base, this glass is essentially unreactive.
