Glass ion exchange method is still widely used in emerging fields such as information display, aerospace, high-speed railway and optical communication, and its corresponding research is in the ascendant. Previous research work on the ion exchange mainly focuses on the mechanism of glass ion exchange to find new ion exchange pairs, which provides a theoretical support to realize higher mechanical and optical properties of glass, the optimization of ion exchange process parameters and the use of modern means such as auxiliary electric field to realize independent control of ion exchange and improve ion exchange rate. Different performance evaluation indexes are proposed for different application scenarios of ion exchange. The performance indexes of ion exchange reinforced glass mainly include surface compressive stress and layer of depth, while the performance index of waveguide glass is mainly refractive index gradient. This review summarized recent research progress on glass ion exchange based on the aspects above.
