Abstract

The chemically strengthened lithium aluminosilicate glass-ceramic with petalite phase has excellent performance and can be used in electronic mobile devices such as electronic display substrates, cover plates and light guide plates. The role of petalite crystals in Li+-Na+ ion exchange is elucidated. The effect of different crystallinity on Li+-Na+ ion exchange in lithium aluminosilicate glass-ceramics was investigated by differential scanning calorimeter (DSC), X-Ray Diffraction (XRD), field emission scanning electron microscope (FESEM), Raman spectroscopy, electron probe micro-analysis (EPMA) and other performance test. The results show that when the glass-ceramic crystals are exchanged with Li+-Na+ ions for more than 10 h, part of the crystals in the exchange layer will decrystallize. The surface stress, Vickers hardness and flexural strength of lithium aluminosilicate glass-ceramic with a crystallinity of 73.6%±3% after Li+-Na+ ion exchange at 450 °C for 6 h reach 418±3 MPa, 7.45±0.1 GPa and 450±3 MPa, respectively.
