Discussion of glass-water interactions. Physical and chemical processes
Leaching data for the alkali and alkaline earth silicate glasses are reviewed. The mechanism is based on the structure being dominated by SiO/sub 4/ tetrahedra forming a random network by sharing their corners (bridging oxygens). Dealkalization of the glass is initiated by the proton adsorption on to the glass surface. The intermediate to long-term interaction is characterized by a steady state between dealkalization and lattice attack such that the leached zone maintains a constant thickness. (DLC)
