    Ultralow expansion glassceramics is a kind of glassceramics with βquartz solid solution as main crystal phase precipitated in parent glass after strictly controlled crystallization on the basis of Li2OAl2O3SiO2 system glass. Because of its low coefficient of thermal expansion, excellent thermal stability, chemical stability and mechanical properties, ultralow expansion glassceramics have been widely used in many fields. In this paper, the composition, preparation method, domestic and international research process and development status, application of ultralow expansion glassceramics are reviewed, and the existing problems in the production of ultralow expansion glassceramics and the gap between the domestic ultralow expansion glassceramics and the top international products, and the development direction of domestic ultralow expansion glassceramics in the future are pointed out.
