Abstract

When soda-lime-silica glass is heated in contact with zinc chloride and lead nitrate melts around strain point of the glass, it is observed that ZnZ+ and PbZ+ ions are introduced in surface layers of the glass (up to 101-'). Average ZnO content up to 41-' from the surface is as high as 5.5 . Depletion of Ca 2+ ions is also observed. The phenomenon of bivalent ion exchange in glass is ascribed to the higher ionic field strengths of ZnZ+ and Pb2+ in comparison to CaZ+, SEM studies of the thermo-chemically treated samples also reveal compositional changes in the surface layers whereas X-ray diffraction patterns do not indicate the presence of any crystalline phase. © 1983 Taylor and Francis Group, LLC.
