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.
