Abstract: Li2O-Al2O3-SiO2 (LAS) system glass-ceramics is widely used in national defense, architecture, chemical industry, biomedicine and other fields due to its low thermal expansion coefficient, high transparency, excellent mechanical properties and other characteristics. In recent years, it has received extensive attention from researchers. This article summarizes the current research status of LAS glass-ceramics, introduces the LAS crystal phase system and related glass products, compares and analyzes the characteristics of various preparation processes of LAS glass-ceramics, and discusses the types of LAS glass-ceramics nucleating agents and their nucleation mechanisms. Finally, the properties, applications, corresponding characterization techniques and testing methods of LAS glass-ceramics are summarized, and the existing problems and future development trends of LAS glass-ceramics are pointed out.

Key words: LAS glass-ceramics, high aluminum and low lithium, low thermal expansion, component design, nucleation agent
