Abstract: Li2O-Al2O3-SiO2(LAS) system glass-ceramics have been widely used in recent years, as their excellent mechanical and optical properties. In this work, the precipitated crystal phase, preparation technique and application of LAS glass-ceramics were introduced. In view of the current urgent demand for high-hard scratch-resistant glass, the current research progress on LAS glass-ceramics strengthening and toughening technology and surface enhancement methods was emphatically expounded. This paper plays an important guiding role in the development of high-strength LAS glass-ceramics in the future.

Key words: glass-ceramics, Li2O-Al2O3-SiO2, β-spodumene, heat treatment process, strengthening and toughening technology, chemical strengthening
