Evaluation of chemical stability of glasses containing lead

Abstract

Evaluation of chemical durability of glass containing lead will be very important in finding a suitable method for its disposal in future. Minute leaching test is needed for the evaluation of the long-term chemical durability of the glass containing Pb which is supposed to be exposed in different kinds of environments. In this study, we investigated leaching behavior of 7.3Na2-6.4K2O-3.7MgO-5.4CaO-66.4SiO2-7.8PbO-3Al2O3(mol%) under a few different pH. Surface of the leached glass was examined by optical microscope and SEM.
