Features of Glass Plate Hardening by the Ion Exchange Method

Abstract:

In this work various methods of glass plate hardening are considered. These plates are used to protect defense devices. As a glass was used system R₂O-B₂O₃-SiO₂. The method of thermal hardening was considered. Technological disadvantages of this method were discovered by analyzing Newton's rings and a polarizing plate. The use of chemical hardening has shown its advantages over the thermal method. The essence of the method is the ion exchange of alkali metals between glass plates and the chemical mixture melt. The operating principle of the chemical hardening equipment and its technology were considered. As a result, hardened glass plates with preservation of planar geometry were obtained.
