Ion Mobility In The Surface Layers Of Soda-Lime-Silicate Glass With Different Thermal History

The mobility of alkaline ions in the surface and near-surface layers of industrial glasses influences the physico-chemical properties such as chemical durability, surface conductivity, adhesion and ion-exchange properties. It is known that not all ions of a glass structure can participate in the diffusion processes. However, most of the applied theoretical models do not consider the existence of ions with different energy of stabilisation in the glass net structure. This work is related to the investigation of the type and concentration of Na and Ca ions that have different mobility in the surface layers of industrial soda-lime-silicate glasses. X-ray micros analysis was used for these purposes.
